Question

(i)
What will be the structure of PF3 and how many valence electrons will be there. ​

Answer 1

Answer:

PF3 is a tetra-atomic molecule where phosphorus donates three valence electrons, and three fluorine atoms accept one electron each to undergo a bond formation and reach a stable condition. 1. It is six in total, where three valence electrons are needed by the phosphorus atom and one, each by three fluorine atoms.

Hope it helps you

Thank you.

Answer 2

Answer:

Conclusion. The Lewis structure of the tetra-atomic phosphorus trifluoride (PF3) molecule shows three fluorine atoms bonded to a single phosphorus central atom. Three single covalent bonds are formed between the phosphorus and fluorine atoms which contributes to the presence of three strong sigma bonds and no pi bonds.
