How nonmetal elements combine by covalent bonds to form compounds.
- Covalent bonds occur between nonmetal atoms.
- The number of bonds depends on how many electrons are in the outer shell.
- Chlorine is only short of one electron so can only form one covalent bond.
- Oxygen is short of two electrons. It can bond with two hydrogen atoms to become water.
All around us, and inside us, the atoms of nonmetals make up an important part of our world.
They include the carbon, hydrogen, oxygen, and nitrogen vital to all living things.
These nonmetal atoms don't normally exist in isolation, but are bonded together to form molecules.
Molecules can be atoms of the ...
