  1. October 12, 2010 Aim: What are some more trends in the periodic table? Do now: Define a trend? Where do we see trends in our everyday life?

  2. First Group: • Alkali earth metals – highly reactive going from top to bottom reactivity increases • Alkaline earth metals – easily loose electrons are almost never found in the atmosphere in their atomic state. • Metalloids – (B, Si, Ge, As, Sb, and Te) have both the metal and non-metal properties. • Noble gasses – un-reactive. Completely filled outer shell. • Halogens – gain only one electron and become -1 charged ion.

  3. 1. ATOMIC RADIUS • For each of the following sets of atoms, rank the atoms from smallest to largest • atomic radius. • a. Li, C, F • b. Li, Na, K • c. Ge, P, O • d. C, N, Al • e. Al, Cl, Ga • 2. IONIC RADIUS • For each of the following sets of ions, rank them from smallest to largest ionic • radius. • a. Mg2+, Si4-, S2- • b. Mg2+, Ca2+, Ba2+ • c. F-, Cl-, Br- • d. Ba2+, Cu2+, Zn2+ • e. Si4-, P3-, O2- Individual Work

  4. 3. IONIZATION ENERGY • For each of the following sets of atoms, rank them from lowest to highest ionization • energy. • a. Mg, Si, S • b. Mg, Ca, Ba • c. F, Cl, Br • d. Ba, Cu, Ne • e. Si, P, He • 4. ELECTRONEGATIVITY • For each of the following sets of atoms, rank them from lowest to highest • electronegativity. • a. Li, C, N • b. C, O, Ne • c. Si, P, O • d. K, Mg, P • e. S, F, He
