1. Covalent
bond:
A
chemical bond formed when two atoms share one or more pairs of electrons with
each other.
2. Ionic
bond:
A chemical bond formed when one atom gains and
a second atom loses electrons. An ion is a molecule or atom that has lost one
or more electrons and is, therefore, electrically charged.
3. Hydrogen
bond:
A chemical bond formed between two atoms or
ions with opposite charges.
4. Polar
bond:
A
covalent bond in which one end of the bond is more positive than the other end.
5. Double
bond:
A covalent bond consisting
of two pairs of electrons.
6. Triple
bond:
A
covalent bond consisting of three pairs of electrons.
7. Multiple
bond:
A
double or triple bond.
8. Electronegativity:
A numerical method for indicating the relative
tendency of an atom to attract the electrons that make up a covalent bond.
