WebAug 15, 2024 · The example coming up should make that clear. 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. WebThe Halogens. Group 7 of the periodic table is home to the Halogens. They are non-metals. They consist of molecules made up of two atoms (diatomic molecules).
