Molecule- a group of atoms held together by covalent bonds that displays all the
properties of that compound. (Usually 2 or more non- metals in covalent bond(s))
Compound- a substance that is formed from different types of atoms and can be broken
into its constituents by chemical reactions.
Fill in the blank
Charged atoms form _ionic_ bonds. Atoms that share electrons form _covalent__ bonds.
The two types of this bond are _nonpolar___ _covalent__ bonds and _polar_____
_covalent_ bonds. Two polar molecules containing hydrogen may bond using
