For each of the following four sets of conditions, enter the formula of the simple ionic compound that could form from the elements X and Z. Give the cationic element first and the anionic element second.
e.g. X3Z5 (if X is the cation) -- subscripts are
inferred.
(Coefficients of "1" are omitted -- as in NaCl)
X has 3 valence electrons and Z has 7 valence electrons:
X has 7 valence electrons and Z has 3 valence electrons:
X has 5 valence electrons and Z has 3 valence electrons:
X has 2 valence electrons and Z has 4 valence electrons:
