The Part of the Atom That is Most Involved in Chemical

Question

The part of the atom that is most involved in chemical reactivity is the
A)proton.
B)neutron.
C)electron.
D)nucleus.

Accepted Answer

The electrons are the particles that are most involved in chemical reactivity because they determine how an atom will bond with other atoms. The number and arrangement of electrons in an atom's outermost energy level, or valence shell, determines its chemical properties and reactivity. Therefore, the movement and transfer of electrons between atoms or molecules is the basis of most chemical reactions.
