Atomic Structure

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.
