Reactivity and Electronegativity
Electronegativity (Pauline scale)
Measure of an atom's ability to attract electrons in a chemical compound
Reactivity increases as you go down the group.
** The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, = higher reactivity.
Reactivity decreases as you go down the group.
** The farther right and up you go on the periodic table, the higher the electronegativity, = harder exchange of electron.
Metals:Reactivity decreases as you go from left to right across a period.
