Question

using the
as\ idea, how many electrons are
eeded\ for the compound pf3? 16 26 32

Explanation:

Step1: Determine the number of atoms

There is 1 phosphorus (P) atom and 3 fluorine (F) atoms in \(PF_3\).

Step2: Calculate the electrons needed for each atom

• Phosphorus (P) needs 8 electrons (octet rule).
• Each fluorine (F) atom needs 8 electrons. Since there are 3 F atoms, the total electrons needed for F is \(3\times8 = 24\) electrons.

Step3: Sum up the electrons

The total electrons needed for \(PF_3\) is \(8+24=32\) electrons.

Answer:

32
