WebJul 4, 2024 · General Properties of the Alkali Metals. Various properties of the group 1 elements are summarized in Table 20.4. 1. In keeping with overall periodic trends, the atomic and ionic radii increase smoothly from Li to Cs, and the first ionization energies decrease as the atoms become larger. WebDuring the formation of some compounds, atoms gain or lose electrons, and form electrically charged particles called ions (Figure 3.3. 1; Video 3.3. 1) Figure 3.3. 1: (a) A sodium atom (Na) has equal numbers of protons and electrons (11) and is uncharged. (b) A sodium cation (Na+) has lost an electron, so it has one more proton (11) than ...
