The most stable isotope of an atom with 12 protons probably has neutrons?

Answer 1

Mass of protons + Mass of neutrons + mass or electrons - Binding energy of the atom. Do not forget to subtract the binding energy. If you teacher never mentioned this, then he/she is wrong. You always have to subtract the binding energy to find the real mass.

Answer 2

The number of protons tell us its identity; the element with atomic number 12 is magnesium. Using the sum of the number of protons and neutrons, we get its Atomic Mass or mass number, which is 22. So it would be the unstable isotope magnesium-22.

Answer 3

The atomic number of an element is equal to its number of protons (or electrons). The atom is magnesium. We can obtain the relative atomic mass by adding the number of neutrons to the number of protons; which is 22 here. The corresponding atom is magnesium-22, which is naturally unstable.

Answer 4

Yes, an atom with 12 protons (which is magnesium) typically has 12 neutrons in its most stable isotope. This is because in a stable atom, the number of protons and neutrons in the nucleus are balanced to achieve stability.

Answer 5

The most stable isotope of an atom with 12 protons probably has 12 neutrons. This is because Mg has 12 protons and most commonly exists as magnesium-24.

Answer 6

Magnesium has 12 electrons, protons and neutrons.

Answer 7

Magnesium, because it is atomic # 12 on the Periodic Table of the elements. Atomic # is determined by the number of protons in an atom.

Answer 8

Magnesium
