Introduction to Atoms

Read each question carefully and answer to the best of your ability.

Everything around us is made of tiny, tiny pieces called atoms. You are made of atoms, your desk is made of atoms, and even the air you breathe is made of atoms! Atoms are so small you cannot see them with your eyes.

Each atom has even smaller parts inside it. Let's learn about them!

1. Everything around us is made of tiny pieces called  .

2. Atoms are so   you cannot see them.

An atom has a center part called the nucleus. Inside the nucleus are two kinds of tiny particles: protons and neutrons.

• Protons have a positive (+) charge.

• Neutrons have no charge (they are neutral).

Around the nucleus, even smaller particles called electrons spin very fast.

• Electrons have a negative (-) charge.

1. What is the center part of an atom called?

2. Which part of an atom has a negative (-) charge?

1. Protons have no charge.

2. Neutrons are found in the nucleus of an atom.

1. Name the three tiny particles found in an atom.
