Term
Ionic Bond
Definition
When one atom takes electrons from another. The atom that takes the electrons becomes negatively charged and the atom that gets rid of the electrons become positively charged.
Term
Covalent bond
Definition
When electrons are shared between atoms.
Term
In a bond if the outer energy level is not full then...
Definition
It is unstable
Term
Isotope
Definition
Atoms of the same element with different numbers of neutrons
Term
Ion
Definition
an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons.
Term
Protons
Definition
Positively charged particles found in the nucleus; have a weight of 1
Term
Neutrons
Definition
Particles with no charge found in the nucleus; have a weight of 1
Term
Electrons
Definition
Negatively charged particles that circle the nucleus; No weight.
Term
Electron Cloud
Definition
Spaces that the electrons occupy as they move around the nucleus
Term
What do electrons determine?
Definition
How an atom will react with other atoms.

Definition
Hydrogen Atoms bonded to an oxygen atom
Term
Carbonyl group
Definition
Carbon atom linked by a double bond to an oxygen atom.
Term
Carboxyl group
Definition
Oxygen double bonded to a carbon that is bonded to a hydroxyl group; act like an acid by giving H+ to solutions.
Term
