Explain, in terms of stable octets of each bonded atom, why fluorine atoms form diatomic molecules when not bonded with other elements, instead of just remaining individual atoms:

Question

Explain, in terms of stable octets of each bonded atom, why fluorine atoms form diatomic

molecules when not bonded with other elements, instead of just remaining individual atoms:

Answer 1

Each F atom has 7 valence electrons and would like to have 8. So, if the 2 F atoms come together and each shares 1 of its electrons with the other, you have a stable diatomic molecule where each F atom now is surrounded by 8 electrosn (octet)
