Diatomic elements gcse
WebA diatomic element is a molecule composed of two of the same atom. The word diatomic comes from ‘di’ meaning two, and ‘atomic’ meaning atom. A monatomic element is stable with just one atom. These diatomic elements are most stable in this paired form because it allows them to follow the octet rule. This means that generally there are ... WebA diatomic molecule is a molecule containing only two atoms. There are seven diatomic elements that you have to remember and a simple mnemonic to help with this.

Suppose you had 123 typical atoms of boron. 23 of these would be 10 B and 100 would be 11 B. The total mass of these would be (23 x 10) + (100 x 11) = 1330. The average mass of these 123 atoms would be 1330 / 123 = 10.8 (to 3 significant figures). 10.8 is the relative atomic mass of boron. the phantom empire 1935
