Answer:
The answer is
valence, tetrahedral, bonding and non bonding,four,zero, tetrahedral, three, one, trigonal bipyramidal
respectively to the following gaps
Explanation:
In CF4 and NF3, the valence electron groups on the central C and N atoms have a tetrahedral arrangement.
The shapes of the molecules are determined by the number of bonding and non bonding of electrons: since CF4 has four bonded atom(s) and zero lone pair(s) of electrons, the shape is tetrahedral.
Since NF3 has three bonded atom(s) and one lone pair(s) of electrons, the shape is trigonal bipyramidal.
