This module discusses the characteristics of different types of matter.
Objective
cite the contributions of the early scientists to the development of the atomic theory; identify and describe the subatomic particles; draw a general picture of the structure of the atom; determine the nuumber of protons, neutrons and electrons in an atom; identify and differentiate the isotopes of an element; identify the atomic orbitals present in each energy level of the atom; and give the number of electrons in each energy level.
