Explain the bond formation of hydrogen molecule.

Text Solution

Verified by Experts

alence shell electronic configuration of fluorine atom is `2s^(2)" "2p_(x)^(2)" "2p_(y)^(2)" "2p_(z)^(1)`
When the half filled `p_(z)` orbitals of two fluorine atoms overlap along the z-axis, a `sigma` covalent bond is formed between them.
