Periodic Table-Metals 2017

Metals, Metalloids and Nonmetals 5

The elements of the periodic table can be broken into three different groups: Metals, Metalloids, and Nonmetals. This periodic table shows the three different groups of elements. The metalloid group separates the metals from the nonmetals. Elements to the left are metals and nonmetals are to the right. The exception is […]
