– hydrogen – carbon – nitrogen – oxygen – phosphorus – sulfur – selenium

What is the difference between metals and nonmetals?

Metals have one to three electrons in their outer shell, whereas non-metals have four to eight electrons. Another difference is that metals tend to lose their valence electrons, but non-metals share or gain valence electrons. Where metals form oxides which are basic, non-metals form oxides which are acidic.

What are the types of non – metals?

Seventeen elements are generally classified as nonmetals; most are gases (hydrogen, helium, nitrogen, oxygen, fluorine , neon, chlorine, argon , krypton , xenon and radon); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine). This image contains all of the discovered elements including non-metals.
