Trends in electronegativity

Electronegativity of an element is defined to be the tendency of an atom to draw electrons toward itself when chemically combined with another element. There are no units for this electronegativity, but it is just to be used as a comparative tool. Larger electronegativities pull electrons to themselves when bonded with other elements. Noble gases don't count when looking at electronegativity. Otherwise, electronegativity increases ⬆️➡️ The periodic table. http://www.chemguide.co.uk/atoms/bonding/electroneg.html
