what determines whether and how much an atom will react with another atom?

• the number of outermost electrons
• the number of neutrons
• its atomic radius
• its atomic mass

Explanation:

The reactivity of an atom is mainly determined by its outermost electrons, also known as valence electrons. These electrons are involved in chemical bonding. Neutrons affect the stability of the nucleus but not reactivity directly. Atomic radius and mass are related to physical properties and some aspects of the atom's behavior but do not directly determine reactivity like valence - electrons do.

Answer:

the number of outermost electrons
