What is the formula for potassium phosphide?

Answer 1

# K_3P#

Since phosphorus has charges of +3, -3, and +5, and potassium almost always has a charge of +1, phosphorus will act as an oxidizing agent with potassium in this situation by removing electrons from potassium to leave it with a negative three charge.

# 3 xx + 1 = 1 xx -3# so it will take three potassium ions to balance one Phosphorus ion. So the formula is

# K_3P#
