Periodic Table. Dmitiri Mendeleev, 1871 Listed the elements in columns in order of increasing atomic mass.

Atoms’ families Remember that columns are groups or families They have similar properties (e.g reactivity, density, etc.) because they have the same arrangement.

The Periodic Table of Elements. Metals, metalloids & non-metals  The periodic table of elements is divided into three categories: metals, metalloids,

Valence Electrons I. Def- Electrons that are found in the outermost energy level or orbital. A. These are the electrons that are involved in chemical bonding.
