Level 4 · Science S4.6

Atoms, bonding and the periodic table

What atoms are made of, how they are arranged, and how they join.

Look inside the atom, follow how the picture of the atom changed, and learn why the periodic table has the shape it has. Then see how atoms join in salts, molecules, diamond and metals, and why each kind of bond gives a material its properties.

For parents and teachers

For learners who can follow a written argument and have met elements, compounds and particles. In many schools this fits learners of about 14 to 16, and older learners can use it as a reference. Each chapter takes two or three short sessions. A learner can work alone: every exercise has its answer and the reason for it. The Try it activities use paper, seeds, stones and salt. Nothing is tasted and nothing is heated. Experiments that need a flame, a strong chemical or mains electricity are described as things scientists do, and the book says why they are not done at home. Keep small seeds and stones away from young children.
