What determines where an element is located on the periodic table?

The periodic table shows all the elements and their physical properties; it is arranged based on atomic numbers and electron configurations.

Explanation:

or An element's location in the periodic table is largely dependent on its electrons; the number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element's block.
