boron
reactive
reactive
it is not reactive to water
one is florine
With a electronegativity of 2,04 on the Pauli scale boron is a reactive chemical element.
yes
florine
it is not reactive to water
Florine conducts thermal energy. Florine is the lightest of halogens and is reactive to most elements, including gas and asbestos.
I think lithium should be more reactive as it has only 1 valance electron wheres Boron has 3 valance electrons. The electro positivity(tendency to lose electrons) of Lithium is greater then Boron, therefore more reactive.
I'd have to go with fluorine.
