Question

ionic compound formulas compound made from lithium and what is the formula for the ionic compound of lit and phosphorus (p)? li is in group 1. and is in group 5a or 15. pli li₃p₅ pli₅ li₃p

Explanation:

Step1: Determine ion charges

Lithium (Li) in group 1 forms a +1 ion ($Li^+$). Phosphorus (P) in group 15 forms a -3 ion ($P^{3 -}$).

Step2: Balance charges

To balance the charges in an ionic - compound, we need 3 lithium ions to balance the - 3 charge of one phosphorus ion.

Answer:

$Li_3P$
