Something else that becomes apparent when looking at this table is that there’s been a tendency for element names to be derived from either the names of people or places more recently. Take two elements from the first column on the periodic table (group 1), sodium and potassium, and one from the second to last column (group 17), chlorine. The natural way to combine these elements turns out to be one sodium atom (Na) for every one chlorine atom (Cl). I wish you a happy life!
