Uses of Bases:
Bases give soaps, ammonia, and many other cleaning products some of their useful properties.
The OH- ions interact strongly with certain substances, such as dirt and grease.

Ions
An ion is an atom or group of atoms in which the number of electron s is different from the number of proton s.
JJ Thomson
he achieved the most brilliant work of his life – an original study of cathode rays culminating in the discovery of the electron.
In 1897 Thomson discovered the electron and then went on to propose a model for the structure of the atom.
John Dalton
Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
John Dalton (1766-1844) was an English chemist, physicist, and meteorologist, best known for introducing the atomic theory into chemistry and for his work on human optics.
Ernest RutherFord
Rutherford (1871–1937) was responsible for a remarkable series of discoveries in the fields of radioactivity and nuclear physics.
He discovered alpha and beta rays, set forth the laws of radioactive decay, and identified alpha particles as helium nuclear
Niels Bohr
Niels Bohr proposed a model of the atom in which the electron was able to occupy only certain orbits around the nucleus.

Erwin Schrödinger
Erwin Schrödinger is best known for the Schrödinger equation, which describes the evolution of the wave function, a quantity that describes the wave properties of a particle
Erwin Schrödinger formulated a wave equation that accurately calculated the energy levels of electrons in atoms.
Molecules
The smallest particle of a substance that has all of the physical and chemical properties of that substance.
Example of Molecules:
-
-
-
-
C6H12O6 (glucose, a type of sugar)
