Introduction

Metal and Non-metals of Class 8

METALS

In the periodic table, you can see a stair-stepped line starting at Boron (B), atomic number 5, and going all the way down to Polonium (Po), atomic number 84. Except for Germanium (Ge) and Antimony (Sb), all the elements to the left of that line can be classified as metals.

Metal and Non-metals

NON METALS:

Except for the elements that border the stair-stepped line, the elements to the right of the line are classified as non-metals (along with hydrogen). Non-metals have properties opposite those of the metals.

METALLOIDS:

The elements that border the stair-stepped line are classified as metalloids. The metalloids, or semimetals, have properties that are somewhat of a cross between metals and non-metals.
