Note that many of the atomic masses, especially the larger ones, are not very close to whole numbers. The atomic masses in Table 3.5 “Selected Atomic Masses of Some Elements” are listed to three decimal places where possible, but in most cases, only one or two decimal places are needed. Table 3.5 “Selected Atomic Masses of Some Elements” lists the atomic masses of some elements a more expansive table is in “Appendix A: Periodic Table of the Elements”. Virtually all elements exist as mixtures of isotopes, so atomic masses may vary significantly from whole numbers. Thus, we use 10.8 u for the atomic mass of boron. The atomic mass of boron is calculated similarly to what we did for our hypothetical example, but the percentages are different: Boron exists as about 20% boron-10 (five protons and five neutrons in the nuclei) and about 80% boron-11 (five protons and six neutrons in the nuclei). This example is similar to a real element. Note that no atom in our hypothetical element has a mass of 10.5 u rather, that is the average mass of the atoms, weighted by their percent occurrence. The sum is the weighted average and serves as the formal atomic mass of the element. A weighted average is found by multiplying each mass by its fractional occurrence (in decimal form) and then adding all the products. What do we mean by a weighted average? Well, consider an element that consists of two isotopes, 50% with mass 10 u and 50% with mass 11 u. The atomic mass of an element is a weighted average of the masses of the isotopes that compose an element. Thus, although it is easy to speak of the mass of an atom, when talking about the mass of an element, we must take the isotopic mixture into account. What is the mass of an element? This is somewhat more complicated because most elements exist as a mixture of isotopes, each of which has its own mass. More exact masses are found in scientific references-for example, the exact mass of uranium-238 is 238.050788 u, so you can see that we are not far off by using the whole-number value as the mass of the atom. Thus, the mass of carbon-12 is about 12 u, the mass of oxygen-16 is about 16 u, and the mass of uranium-238 is about 238 u. There will not be much error if you estimate the mass of an atom by simply counting the total number of protons and neutrons in the nucleus (i.e., identify its mass number) and ignore the electrons. By this scale, the mass of a proton is 1.00728 u, the mass of a neutron is 1.00866 u, and the mass of an electron is 0.000549 u. The atomic mass unit (u some texts use amu, but this older style is no longer accepted) is defined as one-twelfth of the mass of a carbon-12 atom, an isotope of carbon that has six protons and six neutrons in its nucleus. For macroscopic objects, we use units such as grams and kilograms to state their masses, but these units are much too big to comfortably describe the masses of individual atoms and molecules. Individual atoms and molecules, however, are very small, and the masses of individual atoms and molecules are also very small. Express the masses of atoms and molecules.īecause matter is defined as anything that has mass and takes up space, it should not be surprising to learn that atoms and molecules have mass.

The two items at the bottom are r 2 = 0.43969 and r = 0.663. Scroll down to find the values a = –173.513, and b = 4.8273 the equation of the best fit line is ŷ = –173.51 + 4.83 x For now we will focus on a few items from the output, and will return later to the other items. The output screen contains a lot of information. Interpretation: For a one-point increase in the score on the third exam, the final exam score increases by 4.83 points, on average. THIRD EXAM vs FINAL EXAM EXAMPLESlope: The slope of the line is b = 4.83. INTERPRETATION OF THE SLOPE: The slope of the best-fit line tells us how the dependent variable ( y) changes for every one unit increase in the independent ( x) variable, on average. You should be able to write a sentence interpreting the slope in plain English. It is important to interpret the slope of the line in the context of the situation represented by the data. The slope of the line, b, describes how changes in the variables are related. You should NOT use the line to predict the final exam score for a student who earned a grade of 50 on the third exam, because 50 is not within the domain of the x-values in the sample data, which are between 65 and 75. You could use the line to predict the final exam score for a student who earned a grade of 73 on the third exam. If the scatter plot indicates that there is a linear relationship between the variables, then it is reasonable to use a best fit line to make predictions for y given x within the domain of x-values in the sample data, but not necessarily for x-values outside that domain. Remember, it is always important to plot a scatter diagram first. A scatter plot of the data is shown, together with a residuals plot. The owner has data for a 2-year period and chose nine days at random. EXAMPLE:Ī shop owner uses a straight-line regression to estimate the number of ice cream cones that would be sold in a day based on the temperature at noon. By observing the scatter plot of the data, the residuals plot, and the box plot of residuals, together with the linear correlation coefficient, we can usually determine if it is reasonable to conclude that the data are linearly correlated. A box plot of the residuals is also helpful to verify that there are no outliers in the data. It should also show constant error variance, meaning the residuals should not consistently increase (or decrease) as the explanatory variable x increases.Ī residuals plot can be created using StatCrunch or a TI calculator. While a scatter plot of the data should resemble a straight line, a residuals plot should appear random, with no pattern and no outliers. The residuals plot is often shown together with a scatter plot of the data. A residuals plot shows the explanatory variable x on the horizontal axis and the residual for that value on the vertical axis. The difference between these values is called the residual. For each data point used to create the correlation line, a residual y - y can be calculated, where y is the observed value of the response variable and y is the value predicted by the correlation line. Residuals PlotsĪ residuals plot can be used to help determine if a set of ( x, y) data is linearly correlated. r is the correlationĬoefficient, which is discussed in the next section. The slope b can be written as b = r ( s y s x ) b = r ( s y s x ) where s y = the standard deviation of the y values and s x = the standard deviation of the x values. The best fit line always passes through the point ( x ¯, y ¯ ) ( x ¯, y ¯ ). The sample means of the x values and the y values are x ¯ x ¯ and y ¯ y ¯, respectively. Where a = y ¯ − b x ¯ a = y ¯ − b x ¯ and b = Σ ( x − x ¯ ) ( y − y ¯ ) Σ ( x − x ¯ ) 2 b = Σ ( x − x ¯ ) ( y − y ¯ ) Σ ( x − x ¯ ) 2. , 11.įor the example about the third exam scores and the final exam scores for the 11 statistics students, there are 11 data points. Here the point lies above the line and the residual is positive.įor each data point, you can calculate the residuals or errors, y i - ŷ i = ε i for i = 1, 2, 3. In the diagram in Figure 12.10, y 0 – ŷ 0 = ε 0 is the residual for the point shown. If the observed data point lies below the line, the residual is negative, and the line overestimates that actual data value for y. If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. In other words, it measures the vertical distance between the actual data point and the predicted point on the line. The absolute value of a residual measures the vertical distance between the actual value of y and the estimated value of y. It is not an error in the sense of a mistake. The term y 0 – ŷ 0 = ε 0 is called the "error" or residual.

The concept of the atom was revisited and elaborated upon by many scientists and philosophers, including Galileo, Newton, Boyle, and Lavoisier. However, these ideas were largely ignored at the time, as most philosophers favored the Aristotelian perspective. Democritus proposed that different types and combinations of these particles were responsible for the various forms of matter. The Greeks called these particles atomos, meaning indivisible, and the modern word “atom” is derived from this term. This idea was recorded as early as the 5th century BCE by Leucippus and Democritus. Matter is composed of indivisible building blocks. law of multiple proportions: The law stating that reactants will always combine in set whole number ratios. atom: The smallest possible amount of matter that still retains its identity as a chemical element, now known to consist of a nucleus surrounded by electrons.John Dalton, an English chemist and meteorologist, is credited with the first modern atomic theory based on his experiments with atmospheric gases.The idea of an indivisible particle was further elaborated upon and explored by a number of scientists and philosophers, including Galileo, Newton, Boyle, Lavoisier, and Dalton.The ancient Greek philosophers Democritus and Leucippus recorded the concept of the atomos, an indivisible building block of matter, as early as the 5th century BCE.
