Artist 52 [7]2 years ago
6 0

Answer:

D.) This atom has an atomic number of 50

Explanation:

A is wrong because we determine the type of atom by their number of protons, not the number of neutrons. This makes the atom Tin (Sn).

B is wrong because both protons and neutrons contribute to the weight of an atom, not just neutrons

C is wrong because the correct name for this isotope would be tin-119, which is calculated by adding the protons and neutrons

D is correct because isotopes of the same element always share the same atomic number
