Which of the following particle(s) is/are responsible for atoms bonding? Valence electrons
Protons
Neutrons
Positrons

valence electrons

Explanation:

protons and neutrons are in the nucleus, so they do not have anything to do with atoms bonding. positrons also do not have to do with atomic bonding. valence electrons are important as they are the electrons in the outer shell and are needed to complete another electron's outer shell. atoms are stable when their outer shell is full, so atoms without a full outer shell tend to bond with other atoms that would complete theirs.
