Respuesta :

Answer: The magnesium 24, 25, and 26 atoms are isotopes because they all have the same number of protons but they have different mass numbers

Explanation: isotopes of an element have the same number of protons but different mass number. So for magnesium 24, the number of protons is 12 and the number of neutrons is 12.

For magnesium 25, the number of protons would still be 12 but the neutrons would be 13.

Magnesium 26, the number of protons would be 12 and neutrons number is 14
