The reason nonmetals are electrical insulator is since
valence shells in nonmetal atoms are almost full, the atoms attract electrons
and hold them tightly to fill their valence. The reason why it acts as an
insulator is the high ionization energy it has. It prevents any electron from
leaving an atom easily even when an electric field is applied.
C is correct answer.
Compounds is a atoms it has a different elements combine the new molecules.

THE chemical formula of iron is Fe
11.31g/cm3
Explanation:
since density= mass/volume
mass=13
volume of a sphere=4/3πr3
=4/3*3.14*(0.65)^3
=1.149
therefore it becomes,13/1.149
=11.31g/cm
