The formation of #"HF"# from single, isolated #"H"# and #"F"# atoms can be explained using standard enthalpy change of formation.

Under standard conditions, hydrogen and fluorine exist in diatomic gaseous state, #"H"_2# and #"F"_2# respectively.

By forming an equation, we can see the formation of #"HF"#.

#"H"_2+"F"_2 -> "HF"#

Now, all we need to do is balance the equation.

#1/2 "H"_2 + 1/2 "F"_2 -> "HF"#

OR

#"H"_2 + "F"_2 -> 2"HF"#
