GCSE Science Revision: Group 1

GCSE Science Revision: Group 1

In this video, we look at the elements in Group 1, which is also called the Alkali Metals. We look at their physical properties (including density and melting point) and then we look at how they react to form ionic compounds. Finally, we look at how the reactivity of the Group 1 elements increases down the group and explain this in terms of electrons.
