The modern Periodic Table of elements contains 18 groups, also known as families. Each group consists of elements that share similar chemical properties and have the same number of valence electrons. These groups are numbered from 1 to 18 from left to right, with elements in the same group exhibiting trends in reactivity and bonding behavior.
As of 2009, there are 118 elements on the periodic table. Of those, 92 occur in nature. The others are artificially created.
