Beryllium is classified under Period 2.
Group 2A. Alkaline Earth Metal.
Beryllium is an alkaline earth metal. It has an atomic number of 4. By looking at this spot on the periodic table, one finds that beryllium has the atomic symbol Be.
Look at any periodic table: Beryllium #4 Magnesium #12 Calcium #20 Strontium #38 Barium #56 Radium #88
Beryllium Iodide has 1 atom of Beryllium and 2 atoms of Iodine. BeI2 is the correct formula for this compound.
Beryllium has greater ionization energy, with 899 kJ/mol versus Germanium's 762 kJ/mol. The general trend (most prominently displayed in the representative elements) in the periodic table is increasing ionization energy across a period, and decreasing ionization energy down a group.
Group 2, period 2
beryllium, Be
In the periodic table, it is classified as an alkali earth metal, so yes, it is a metal.
