which of the following is not a correct statement from the lewis theory of bonding?
a full valence shell of electrons may be achieved by the sharing of electrons between non - metal atoms.
electrons are most stable when they are unpaired.
atoms and ions are stable if they have a full valence shell of electrons.
the sharing of electrons results in a covalent bond.

Explanation:

• According to Lewis Theory of Bonding, electrons are most stable when they are paired (as in a full valence shell).
• Option A: Non - metal atoms share electrons (covalent bonding) to achieve a full valence shell.
• Option C: Atoms and ions with a full valence shell (like noble gas configuration) are stable.
• Option D: Sharing of electrons is the basis of covalent bond.

Answer:

B. Electrons are most stable when they are unpaired.
