Elements vs Compounds Atoms are the tiny units, which collect up to form all the existing chemical substances. Atoms can join with other atoms in various ways, thus form thousands of molecules and other compounds. According to their electron donating or withdrawing abilities, they can form covalen...

These elements exist as diatomic molecules. H, O, N etc. cannot exist in nature as single atoms. They are always paired (H 2 , O 2 , N 2 ). Composition of Elements and Compounds Free, or elemental hydrogen (H 2 ) is found in volcanoes; It can be prepared in ...
Compounds come in two varieties: molecules and, well, compounds. All compounds are molecules, but not all molecules are compounds. Compounds must be made up of two or more elements. Molecules can be made up of two atoms of the same element, like O2. ...
