Answer 1

Answer #1

A compound has formula XCl₂

XCl₂ has X²⁺ ion and Cl^- ion

Ion X contains 20 electrons

X lost two electrons to become X²⁺. X²⁺ has 20 electrons

$\Rightarrow$ X has 22 electrons

Element which has 22 electrons is Titanium (Ti)

Thus the ion is Ti²⁺

The correct formula for carbonate ion is CO₃^2-
