Electronegativity Periodic Trend - Using the Periodic Table to help determine electronegativity!
Electronegativity is the tendency of an atom to gain an electron. The way I think about it is like tug of war. The stronger an atom can pull in an electron, the higher it’s electronegativity will be. The trend for electronegativity is...
