An introduction to atoms and elements including chemical symbols, diatomic molecules and molecular formulae. Examples of elements found in everyday objects are given, such as aluminium in a drinks can, carbon in charcoal and gold in an earring. The idea of chemical symbols is introduced and the conventions for chemical symbols are explained. This is followed by a description of molecules such as oxygen, nitrogen and chlorine including their formulae.

An activity with coloured beads could be used to reinforce the idea about atoms. They could decide to either leave them as individual atoms or combine into diatomic molecules. They could then use this to give examples from the periodic table of single atom elements and diatomic molecules. A quiz could be created to introduce a competitive element to reinforce their learning.

Two presenters use animations to show how protons, neutrons and electrons make up atoms. They explain the relative masses, sizes, locations and charges of these subatomic particles.

Students could explain the differences between protons, neutrons and electrons. After watching the clip, students could explain in their own words what they have learned using different examples from the periodic table.

All substances are made from tiny particles called . An atom is the smallest part of an that can exist.

Atoms of each element are represented by their own chemical symbol. A chemical symbol:

consists of one or two letters

always starts with a capital letter, with any other letter in lower case

For example the symbol O represents an atom of oxygen, and Na represents an atom of sodium. You must write the chemical symbol of sodium as Na, not as NA, na or nA.

There are over 100 different elements. The names and symbols of the elements are shown in the periodic table. Elements are arranged into groups with similar properties. Groups are numbered from 1 to 7, then 0.

In the periodic table, metals are on the left of the stepped line, and non-metals are on the right.

Mixtures

# data[].attributes.attachment_link.readable_text
The word 'pure' is used in chemistry in a different way from its everyday meaning. For example, shops sell cartons labelled as 'pure' orange juice. The label means that the contents are just orange juice, with no other substances added. However, the juice is not pure in the chemical sense, because it contains different substances mixed together. In chemistry:

The substances in a mixture can be elements, or compounds, or both. Being part of a mixture does not change the chemical properties of the substances that are in it.

Separating mixtures

Mixtures can be separated by physical processes. These processes do not involve chemical reactions, and no new substances are made.

An explanation of how the mass of atoms varies depending upon the element. Gold and silver rings are shown and an explanation of why the gold ring is heavier is given. The fact that gases also have mass is described. This is explained by stating that an opened bottle of lemonade is lighter than an unopened one. The mass of Helium being lighter than air is also mentioned.

This clip shows students why some elements are heavier than others, and show that gases also have a mass. Can students think of other everyday examples that highlight the fact that similar sized objects have different masses?
