Chemical compound
A chemical compound is a
chemical substance
consisting of two or more
different chemically bonded
chemical elements, with a
fixed ratio determining the
composition. The ratio of
each element is usually

Chemical bond
A chemical bond is the
physical phenomenon of
chemical substances being
held together by attraction
of atoms to each other
through sharing, as well as
exchanging, of electrons -or
electrostatic forces. In
