Question

How are protons, neutrons, and electrons related to an element's placement in the periodic table?

Answer 1

Answer:

Explanation

The number of outer shell electrons determines the group number of the element. The number of occupied principle quantum shells (energy levels) determines the period of the element. The proton number determines the element itself and its position.

The position of each element in the table gives important information about its structure, properties, and behavior in chemical reactions. Specifically, an element's position in the periodic table helps you figure out its electron configuration, how the electrons are organized around the nucleus.
