Question

Why fluorine is more reactive than chlorine ?...{2 marks }

Answer 1

chlorine is less reactive than fluorine because the outer electrons in a chlorine atom are further from the nucleus than the outer electrons in a fluorine atom. It is harder for a chlorine atom to gain an electron than it is for a fluorine atom.

Answer 2

Answer:

Fluorine is more reactive than chlorine because of its lower bond energy than chlorine.

Explanation:

Fluorine and Chlorine are the elements of the Halogens which require a single electron to form an octet configuration.

Fluorine is more reactive than chlorine because of the lower bond energy.

Bond Energy is defined as the amount of energy required to break one mole of bonds of a particular type in the gaseous state.

The outer electrons in a Fluorine atom are closer to the nucleus than the outer electrons in a Chlorine atom. Hence it is easier for the fluorine atom to gain an electron than it is for chlorine.
