For molecule NF3-
a) draw a full MO diagram. All F 2pz LGO are non-bonding. The 2s orbitals are to far from 2p to interact. The e LGO derived from F 2px and 2py orbitals (depends on central atom with e symmetry exist, then the 2py LGO wil either be bonding or not)
b) what are the symmetries of valance orbitals on central N atom
