Question

After a covalent bond has stabilized an atom, the atom will have

fewer valence electron shells.
more valence electron shells.
an empty valence electron shell.
a full valence electron shell.

Answer 1

the answer is a full valence electron shells

hope this helps (;

Answer 2

• The atom have a full valence electron shell.

Step-by-step explanation:

• My question is that why covalent bonds take place?

Every atoms tends to from bond with another atoms in order to get nearest electronic configuration of nobel gases. They become stable when their valence shell become complete. So when covelant bond forms between atoms, share electrons to each other and stabilize themselves.
