Question
  1. The Periodic Table is named after the periodicity or repeating rise and fall of certain attributes. Figure 2.3 shows what periodic trend? What periodic trend is shown in Figure 2.4?
Figure 2.4 A graph of melting point versus atomic number shows periodic properties similar to the trend in Figure 2.3 D. While the maxima and minima are not as sharp as in Figure 2.3O, the change in melting points of the elements still shows a similar periodic trend. Melting Point versus Atomic Number 4500 4000 W 3500 Mo E 3000 2500 Ti Th 2000 Si 1500 Ge Sb 1000 500 0. 10 20 30 40 50 60 70 80 90 100 Atomic number Carbon, the element on which life is based, is a group 4A nonmetal near the top right of the periodic table. Clustered near carbon are other elements often found in living organisms, including oxygen, nitrogen, phosphorus, and sulfur. We will look at the subject of organic chemistry-the chemistry of carbon compounds-in Chapters 12 17 and move on to biochemistry-the chemistry of living things-in Chapters 18 290. Temperature (K)

Figure 2.3 A graph of atomic radius in picometers (pm) versus atomic number shows a periodic rise and fall pattern. The maxima occur for atoms of the group 1A elements (Li, Na, K, Rb, Cs, and Fr in red); the minima occur for atoms of the group 7A elements (blue). Accurate data are not available for the group 8A elements. 300 Cs Fr Rb 250 K 200 Na Li 150 At 100 Br 50 0. 0. 90 10 20 30 40 50 60 70 80 100 Atomic number There is nothing unique about the periodicity of atomic radii shown in Figure 2.3 . The melting points of the first 100 elements, for example, exhibit similar periodic behavior, as shown in Figure 2.4 , with a systematic trend of peaks and valleys as you progress through the elements in the periodic table. Many other physical and chemical properties can be plotted in a similar way with similar results. In fact, the various elements in a given group of the periodic table usually show remarkable similarities in many of their chemical and physical properties. Look at the following four groups, for example: G 595 FEB CC étv W Atomic radius (pm)
