• 1. Identify the building blocks of matter.

• Atoms

• Meaning of the term ATOM
• Around 2,500 years ago, the ancient Greek
  philosopher, Democritus, was sitting around just
  thinking. He was thinking about cutting stuff up
  and came up with the idea that there must be a
  point where you could no longer cut something any
  smaller. He named the atom after the Greek word
  atomos, which means 'that which can't be split.'

8

• Atomos
• That which cannot be cut.
• Indivisible

9

• 2. Identify the subatomic particles that make up
  an atom.

• Protons, neutrons and electrons

10

• 3. What is an elements atomic number?

• The number of protons in an atom.

11

• Identify the atomic number of oxygen. Support
  your answer.

12

• Observe the diagram below of a Carbon atom.
  Identify the atomic number. Support your answer.

13

• 4. Describe what the nucleus of an atom consists
  of.

• Protons and Neutrons

14

• 5. Where are elections located in an atom?

• Outside the nucleus

15

• Orbit the nucleus in the electron cloud.

16

• 6. Explain the meaning of the phrase neutrons
  are neutral.

Neutrons

• Neutrons do not have a charge.
• Neutrons are neither NEGATIVE or POSITIVE.

17

• 7. Fill in the table below with the appropriate
  charge of each particle.

Protons
Neutron
Electron

SUBATOMIC PARTICLE CHARGE (positive, negative or neutral) LOCATION of subatomic particles (inside the nucleus OR outside the nucleus)
Protons
Electrons
Neutrons
POSITIVE
INSIDE THE NUCLEUS
NEGATIVE
OUTSIDE THE NUCLEUS
NEUTRAL
INSIDE THE NUCLEUS
