Answer #1

P has 5 valence electrons and hence it forms 5 bonds

[Double bond with O and single bond with each Cl]

V has 5 valence electrons (3 in d orbital and 2 in s orbital). So, it can form similar compound

Ge has 4 valence electrons (2 in p orbital and 2 in s orbital). So, it can’t form similar compound

Ga has 3 valence electrons (2 in p orbital and 1 in s orbital). So, it can’t form similar compound

Cr has 6 valence electrons (2 in p orbital and 4 in d orbital). So, it can’t form similar compound
