an atom of element be has four protons, four electrons, and five neutrons. which element below could be an isotope of this atom?\no sodium - 10\no beryllium - 10\no boron - 9\no carbon - 9

Answer

Brief Explanations:

Isotopes are atoms of the same element with different numbers of neutrons. The given atom is beryllium (Be) with 4 protons. An isotope must be of the same element, beryllium. Beryllium - 10 is an isotope of beryllium as it has the same number of protons (4) but a different number of neutrons compared to the given beryllium atom.

Answer:

beryllium-10
