Question

according to the chemthink tutorial; what is true about a proton? charge choose mass choose in the nucleus +1 zero responsive for reactivity determines the identity of the atom heavy location role in the atom choose

Explanation:

Protons have a positive charge of +1, are located in the nucleus of an atom, and the number of protons determines the identity of the atom. They are relatively heavy compared to electrons. Reactivity is mainly determined by the number of valence electrons.

Answer:

charge: +1
mass: heavy
location: in the nucleus
role in the atom: determines the identity of the atom
