Question
For each of the following, write down the name of the family to which they belong and the number of valence electrons calcium lithium chlorine argon Give the electron configuration for each of the following atoms or ions. Al Mg^2+ N^Ca^2+ For each of the following pairs of atoms, give the formula of the ionic compound formed and name each compound. Mg and Cl Ca and O Li and N Write down the names for each of the following: CaSO_4 Al(OH)_ Give the formulas for the following compounds: sodium carbonate ammonium phosphateExplanation / Answer
1) Calcium---II group element--valence e-s are 2 ([Ar]4s2)
Lithium----I group element--valence e-s are 1 ([He]2s1)
Chlorine--- VII group element--valence e-s are 7 ([Ne]3s23p5)
Argon----VIII group or zero group element--valence e-s are 8 ([Ne]3s23p6)
2) Al - 1s2,2s2,2p6,3s2,3p1
Mg^2+ = 1s2,2s2,2p6
N^3- = 1s2,2s2,2p6
Ca^2+ + 1s2,2s2,2p6,3s2,3p6
3) Mg and Cl --- MgCl2 ---Magnesium chloride
Ca and O --- CaO ---Calcium oxide
Li and N -- Li3N --- Lithiun nitride
4) CaSO4 ----- Calcium sulfate
Al(OH)3 ---- Aluminium hydroxide
5) Sodium carbonate --- Na2CO3
Ammonium phosphate --- (NH4)3(PO4)
