Question

Quizplus · Accepted Answer

Electrons are negatively charged and participate in chemical bonding, making them responsible for the chemical behavior of atoms.

Answer: A and E (if C is not accepted) 
 Protons are positively charged, but they do not participate in chemical bonding. However, they do determine the atomic number and therefore the identity of the element. Ions are atoms that have gained or lost electrons, leading to a change in their charge and chemical behavior.
