Which have different numbers of electrons? different ions of an element different isotopes of an element the nucleus of an element each of the atoms of an element

Different ions of an element

Explanation:

From the options given, it is only the different ions of an element that can have different electrons.

This is because ions carry charge which could be positive or negative due to a deficit or excess of electrons.

A cation would be formed if there is a deficit of electrons and the atom becomes positively charged, and an anion would be formed if there is an excess of electrons and the atom becomes negatively charged.

For different ions of the same element, the electron number would vary and this would thus lead to each different ion carrying a greater or lesser charge than the other ions of the same element.

Different numbers of electrons occurs in different ions of an element.

Different isotopes of an element have the same number of number of protons and electrons but different number of neutrons.

Different ions of an element have different number of electrons.

For cations, such as;

Thus, we can conclude that different numbers of electrons occurs in different ions of an element.
