The nonmetals are a diverse group of elements scattered around the top half of the periodic table. They continually get more scarce as you go down the periodic table. They are all versatile elements with many uses, and are very important for life on Earth. For example, hydrogen, oxygen, nitrogen, phosphorus, and carbon are all present in DNA and are important constituents for all living beings.
There are 6 most common nonmetals (some tables may or may not display more or less nonmetals)
Group 1
Hydrogen -electron configuration: 1s1 -Van der Waals radius: 120 pm
Group 14
Carbon -electron configuration: [He]2s2 2p2-Van der Waals radius: 170 pm
Group 15
Nitrogen -electron configuration: [He]2s2 2p3-Van der Waals radius: 155 pm
Phosphorus -electron configuration: [Ne]3s2 3p3-Van der Waals radius: 195 pm
Group 16
Oxygen -electron configuration: [He]2s2 2p4- Van der Waals radius: 152 pm
Sulfur -electron configuration: [Ne] 3s2 3p4- Van der Waals radius: 180 pm
