AAn electron pair
BA single proton
CA whole neutron
DAn entire atom
Answer & Solution
Correct answer: A. An electron pair
1. Lewis generalised the acid-base idea beyond protons.
2. Lewis proposed a generalized definition of acid-base behavior.
3. In it, acids and bases are identified by their ability to accept or to donate a pair of electrons.
4. Doing so forms a coordinate covalent bond.
