4. What kinds of particles are found in the Air? Learning objective: To be able to Identify and describe the basic structure of an atom. Lesson 1: Atomic Structure

5. What particles are atoms made of? Atoms are the building blocks of matter. For some time, people thought that atoms were the smallest particles and could not be broken into anything smaller. Proton- positive Neutron -neutral Electron-negative Scientists now know that atoms are actually made from even smaller particles. There are three types: These particles inside an atom is called as subatomic particles . How are these particles arranged inside the atom? Learning objective: To be able to Identify and describe the basic structure of an atom. Lesson 1: Atomic Structure

6. How are these particles arranged inside the atom? Protons, neutrons and electrons are not evenly distributed in an atom. The electron s are spread out around the edge of the atom. They orbit the nucleus in layers called shells. The protons and neutrons exist in a dense core at the centre of the atom. This is called the nucleus.

21. Why do atoms have no overall charge? Challenge Question Learning objective: To be able to Identify and describe the basic structure of an atom. Lesson 1: Atomic Structure

22. Why do atoms have no overall charge? The total number of electrons in an atom is always the same as the number of protons in the nucleus. This means atoms have no overall electrical charge. = PROTONS + ELECTRONS NO CHARGE Learning objective: To be able to Identify and describe the basic structure of an atom. Lesson 1: Atomic Structure

23. Charges are balanced! So no charge overall! Learning objective: To be able to Identify and describe the basic structure of an atom. Lesson 1: Atomic Structure
