To write the formula for sodium phosphide, you'll need to combine sodium and phosphorus, considering their respective charges to balance the overall charge of the compound.
Sodium (Na) is an alkali metal and forms a cation with a +1 charge (
Na
+
Na
+
).
Phosphorus (P) in sodium phosphide is typically in the form of the phosphide ion with a -3 charge (
P
3
−
P
3−
).
To balance the charges, you need three sodium ions to balance one phosphide ion. So, the formula for sodium phosphide is:
