What are atoms with same atomic mass but different atomic numbers called?

Answer 1

Isotopes. The isotope has the same number of protons and electrons as the regular atom, but has more (or sometimes less) neutrons, and therefore its atomic mass is more (or less, depending on whether the neutrons have increased or decreased).

Answer 2

Atoms with the same Atomic Mass but different atomic numbers are called isotopes. Isotopes have the same number of protons but different numbers of neutrons in their nucleus, which results in differences in atomic number.

Answer 3

Isotopes
Ions! (they have different amounts of electrons, usually due to bonding, but all go under same atomic number)

Answer 4

Atoms of the same element that have different mass numbers are called isotopes. They are different because of the number of neutrons in the nucleus can vary

Answer 5

Isobars have the same atomic mass.

Isotones have the same number of neutrons.

Isotopes have the same atomic number (number of protons).

Answer 6

Isotopes. They differ in the number of neutrons in the nucleus.

Answer 7

They are called isotopes.

Answer 8

Isotopes.

Answer 9

Isotopes

Answer 10

isotopes
