I think she is wrong because if it is phosphorus TRIchloride then as it says in its name there are three atoms of chlorine in it, not four.
Answer:
She is incorrect
Explanation:
According to the question the compounds name is phosphorus trichloride . Phosphorus trichloride can be simply translated as PCl3 . The tri indicates that the chlorine atom exist as 3 atom of chlorine .
phosphorus has an atomic number of 15 and chlorine has an atomic number of 17. Phosphorus has electronic configuration of 2 8 5 , that means it requires about 3 electrons to satisfy the octet rule. Chlorine has a configuration of 2 8 7. Phosphorus atom shares electrons with the 3 atoms of chlorine. Phosphorus is covalently bonded with chlorine sharing 3 pairs of electrons.
Phosphorus trichloride PCl3 has 1 atom of phosphorus and 3 atoms of chlorine and not 4 atoms of chlorine. Laura is definitely incorrect.
