Electrons

Atomic number

Explanation:

The question describes a period table which is a chart of the elements.

The Periodic Table of elements shows the arrangement of elements based on their increasing atomic number.

In a neutral atom, the number of electrons will equal the number of protons, so we can easily determine electron number from atomic number. In addition, the position of an element in the periodic table—its column, or group, and row, or period—provides useful information about how those electrons are arranged (electronic configuration) in their different shells.
