The lewis dot model of a molecule is shown. a visual diagram of a pcl3 molecule is shown. phosphorous is the central atom with a horizontal line connecting to each of the three chlorine atoms around it. phosphorous has a pair of dots on it. each of the three chlorine atoms have a pair of three dots on it. based on the model, which of the following is true?
( a. the electronegativity difference between phosphorous and chlorine is greater than 1.7.
( b. each chlorine has three non-bonded pairs and one bonded pair of electrons.
( c. phosphorous has three non-bonded pairs and one bonded pair of electrons.
( d. phosphorous has three valence electrons in the outermost energy level.
