Periodic Table Basics

An element is a pure substance that cannot be broken down chemically and is made up of only one kind of atom.

The noble gases are located on the far right side of the periodic table.

The dark zig-zag line separates metals from non-metals, with metals on the left side.

Sulfur (S) is most similar to oxygen (O) in terms of shared properties.

Noble Gases do not want to bond to or react with other elements.

The main categories are metals, non-metals, and metalloids.

A compound is a substance formed when two or more different elements chemically bond together.

Alkali metals are highly reactive elements found in Group 1 of the periodic table.

Halogens are reactive non-metals found in Group 17 of the periodic table.

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.
