When Atoms Complete Their Outer Electron Shell by Sharing Electrons

Question

When atoms complete their outer electron shell by sharing electrons, they form
A) ionic bonds.
B) covalent bonds.
C) hydrogen bonds.
D) anions.
E) cations.

Accepted Answer

When atoms complete their outer electron shell by sharing electrons, they form covalent bonds. In covalent bonds, the participating atoms share one or more pairs of valence electrons. This allows each atom to complete its outermost energy level, hence stabilizing the molecule.
