Atomic Structure

By: Mr. Jonathan S. Juan

Objectives

Describe the structure of atoms including the masses, electrical charges, and locations of protons, neutrons and electrons.
Identify that proton is an element’s specification.
Determine the number of protons, neutrons and electrons of an element by
using the periodic table.
Identify the components, location, charge and names of subatomic particles in atoms.

Explain the atoms are the smallest particles of matter and are made up of protons, neutrons, and electrons.
Differentiate between protons, neutrons, and electrons in terms of their mass, electrical charges, and location within the atom.
Explain how the atomic theory has changed as scientists have discovered new information about the atom.
