The basic parts of the Periodic Table are:
Elements: There are 118 elements that we know of right now. Each element has its own special one- or two-letter symbol.
Atomic Number: This is how we identify an element. It tells us how many protons are in the center of an atom. For example, Hydrogen has an atomic number of 1 because it has one proton.
Mass Number: This number shows how many protons and neutrons are in the atom's center. Different versions of the same element can have different mass numbers.
Groups and Periods: The table is set up in a special way:
States of Matter: Elements can be solid, liquid, or gas at room temperature. Out of all the elements, 11 are gases, 2 are liquids, and the rest are solids.
