1G2 Science Chapter 8 Atoms and Molecules

Lesson Objectives

At the end of the topic, you should be able to:

Compare the size of an atom with the size of everyday object.
show an appreciation of how, in practice, models are constructed, justified and continuously revised as they are used to probe new phenomena and collect additional data (e.g., the various atomic models)

Lesson Objectives

At the end of the topic, you should be able to:

describe an atom as an entity that is electrically neutral and is made up of a positively charged nucleus (protons and neutrons) with negatively charged electrons moving around the nucleus
recognise that atoms have mass that is mainly contributed by the mass of the nucleus
