Which is more reactive sodium or lithium.why?
- sodium is more reactive than lithiun
- as you move down the group in a periodic table the mettalic properties of an element increases as the atomic radii increases resulting in increase in ability to lose electrons.
- the ability to lose electrons increases as the efective nuclear chatge on the outermost shell decreases
and remember that reactivity is based on the ability to lose or gain electrons
one who can give or lose more electrons than others is more reactive
therefore sodium is more reactive than lithium
