Kr: 36, 4, 18, Noble gases, 8, 36, Non - metal, No, Gas, 0;
Ca: 20, 4, 2, Alkaline earth metals, 2, 20, Metal, Yes, Solid, +2;
S: 16, 3, 16, Chalcogens, 6, 16, Non - metal, No, Solid, - 2;
Ga: 31, 4, 13, Post - transition metals, 3, 31, Metal, Yes, Solid, +3;
Sb: 51, 5, 15, Pnictogens, 5, 51, Metalloid, Yes, Solid, +3/ - 3.
