Question

Which statement about one atom can definitively tell you the identity of the element? a. The atom has 1 proton. b. The atom has 2 neutrons. c. The sum of the number of protons and neutrons in the atom is 3 d. The difference between the number of neutrons and protons in the atom is 1.

Answer: 2(B)

Explanation: It's a little confusing to read but from my understanding it's 2 because the atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons
