What is true of a covalent bond? (03.03)
it is the electrostatic attraction between oppositely charged particle
it is the sharing of electrons by overlapping orbitals
it involves the exchange of electrons from one atom to another
it involves the sharing of neutrons between two nuclei

I think B..

Explanation:

It is the sharing of electrons from one atom to another .

The answer is b: It is the sharing of electrons by overlapping orbitals

Explanation:

The ionic bong involves the exchange of electrons from one atom to another to keep eight particles in their outermost orbit. In this way the atoms become stable.  This happens between a metal, which losing electrons becomes a cation that now has a positive charge, and a non-metal, which accepting electrons becomes an anion that now has a negative charge. So the ionic bond is the electrostatic attraction between oppositely charged particle (cation and anion).

No chemical bond involves sharing neutrons between two nuclei. Chemical bonds occur between the electrons of atoms, which are found in the outer layer around the nuclei.

So, the correct answer is b: It is the sharing of electrons by overlapping orbitals.  This happens between two non-metallic elements.

it is the most commonly accepted one
