Each square on the periodic table includes lots of information about ?

Each square on the periodic table, commonly referred to as an "element cell," includes several important pieces of information about the chemical element it represents. Here is the information typically provided in each square:

1. Atomic Number: This is usually the topmost number in the square and it represents the number of protons in the nucleus of the atom. It defines the identity of the element and its position on the periodic table.

2. Element Symbol: This is generally in the center of the square and is one or two letters that are an abbreviation for the chemical element's name, often derived from its English, Latin, or other originating language name.

3. Element Name: The full name of the chemical element. In some periodic tables, the element name may not be included in the square due to space constraints but is implied by the element symbol.

4. Atomic Mass (also called Atomic Weight) : Usually found at the bottom of the square, the atomic mass represents the average mass of an atom of the element. It accounts for the various isotopes of the element and their relative abundance.
