Answer to Question #212663 in Chemistry for Faith

Question

An ion compound contains an unknown ion X and has the formula X3N2. Ion X contains 10 electrons write down the chemical symbol of X.

Answer 1

Solution:

X₃N₂ → 3X²⁺ + 2N^3-

Number of electrons in X²⁺ ion = 10

Therefore,

Number of electrons in X = 10 + 2 = 12

Number of electrons in X = Number of protons in X = Atomic number of X = 12

Thus, X²⁺ = Mg²⁺ - magnesium ion

X = Mg

Answer: Mg²⁺
