The Non-Metal elements

Post by Algerien1970 on Wed 20 May - 11:32


Non-metals are the elements in groups 14-16 of the periodic table. Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. The non-metals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon). The non-metals have no metallic luster, and do not reflect light. They have oxidation numbers of ±4, -3, and -2.


The Non-Metal elements are:


Hydrogen
Carbon
Nitrogen
Oxygen
Phosphorus
Sulfur
Selenium
