A positive ion has fewer electrons than a neutral atom of the same element.

Here's why:

* Neutral Atoms: Atoms have an equal number of protons (positive charge) and electrons (negative charge), making them electrically neutral.

* Positive Ions: A positive ion is formed when an atom loses one or more electrons. This loss of negatively charged electrons leaves the ion with a net positive charge.

Example: Sodium (Na) has 11 protons and 11 electrons. When it loses one electron, it becomes a sodium ion (Na+) with 11 protons and 10 electrons.
