When Would an Atom Be Least Likely to Form Chemical

Question

When would an atom be least likely to form chemical bonds with other atoms?
A) The number of protons equals the number of electrons.
B) The number of protons equals the number of neutrons.
C) There is only one electron in the valence shell.
D) The valence shell is full of electrons.

Accepted Answer

When the valence shell of an atom is full with electrons, it has achieved a stable configuration and is therefore least likely to form chemical bonds with other atoms.
