Answer to Question #213458 in Chemistry for sliq

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: Mg
