Question

17 which subatomic particle identifies the element? a) the number of neutrons b) the number of electrons c) the number of protons d) its charge

Explanation:

In chemistry (a subfield of Natural Science), the atomic number, which is the number of protons in an atom's nucleus, uniquely identifies an element. Neutrons can vary (isotopes), electrons can change (ions), and charge depends on electron/proton balance. So the number of protons determines the element.

Answer:

C. the number of protons
