Which Subatomic Particle Determines the Chemical Activity of an Atom

Question

Which subatomic particle determines the chemical activity of an atom?
A)Neutron
B)Proton
C)Electron
D)Prion

Accepted Answer

The electron is responsible for determining the chemical activity of an atom because it is involved in chemical bonding with other atoms. Protons and neutrons are found in the nucleus and do not play a significant role in chemical reactions. Prions are not subatomic particles, but rather infectious proteins that can cause disease.
