composition of atoms quick check\nwhat determines an atom’s identity? (1 point)\nthe number of neutrons\nthe number of protons\nthe number of electrons\nthe valence number

Answer

Brief Explanations:

The atomic number, which is determined by the number of protons in the nucleus of an atom, defines what element the atom is. Different elements have unique numbers of protons. Neutrons affect the isotope of an atom, electrons are involved in chemical bonding and can change in number in ions, and valence number relates to an atom's reactivity and bonding capacity, not its identity as an element.

Answer:

the number of protons
