WebDec 8, 2024 · The electronegativity increases going from left to right, and it decreases going down the table. Mass: As you go from left to right and from top to bottom, you are always adding more protons in the atom. This has the general trend to make the later elements heavier than the earlier elements.

WebOn the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.
