Elements and compounds | CPD | RSC Education

A useful starting point is to show elements and compounds being formed (see table). Ask students to think about what is present at the start and end of each reaction. For example, sodium doesn't 'disappear' when it reacts with chlorine, it's incorporated into a compound. And sodium chloride has very different properties to elemental sodium.

How elements are formed — Science Learning Hub

Elements and the 'Big Bang' theory. During the formation of the universe some 14 billion years ago in the so-called 'Big Bang', only the lightest elements were formed – hydrogen and helium along with trace amounts of lithium and beryllium. As the cloud of cosmic dust and gases from the Big Bang cooled, stars formed, and these then grouped together to form galaxies.
