Question

Nitrogen ,oxygen, fluorine which element is most reactive and why?

Answer 1

Fluorine is the most reactive because it has to gain only 1 electron to get Nobel gas configuration. So, out of the three elements given above, Fluorine is the most reactive Bcoz it needs less force to attain Nobel gas configuration.

Hope it may help you..

Thank you..

Answer 2

Fluorine is more reactive .this is because ,in fluorine,the electronic configuration is 1s2 2s2 2p5 and it requires only one electron to attain stable configuration.and it is also due to small size of fluorine and high electronegativity that's why fluorine is most reactive element.
