an atom of element be has four protons, four electrons, and five neutrons. which element below could be an isotope of this atom? sodium - 10 beryllium - 10 boron - 9 carbon - 9

an atom of element be has four protons, four electrons, and five neutrons. which element below could be an isotope of this atom? sodium - 10 beryllium - 10 boron - 9 carbon - 9

Answer

Explanation:

Step1: Recall isotope definition

Isotopes are atoms of the same element with different numbers of neutrons.

Step2: Identify element

The given atom is of beryllium (Be) as it has 4 protons (atomic number of beryllium is 4).

Step3: Select isotope

An isotope of beryllium - 9 (with 4 protons and 5 neutrons) would be another beryllium atom with a different number of neutrons. Beryllium - 10 is an isotope of beryllium.

Answer:

beryllium - 10
