Given element X with valency 3
1)Phosphide means compound of X with P [phosphide valency 3]
chemical formula would be:
X3P3
hence XP is the chemical formula of its phosphide compound.
2) Carbonate valency 2
chemical formula would be
X2(CO)3
3) The element X should be metal because Phosphorous AND CARBON ARE nonmetals.
