Question

the charge on the iron ion in fecl₂ is
o a. +3
o b. -2
o c. +1
o d. +2

Explanation:

Step1: Determine the charge of \( Cl^{-} \)

The charge of \( Cl^{-} \) is \( - 1 \).

Step2: Set up an equation for the overall charge of \( FeCl_{2} \)

Let the charge of \( Fe \) be \( x \). For the compound \( FeCl_{2} \), using the formula \( x+2\times(-1)=0 \) (since the overall charge of a neutral compound is \( 0 \)).

Step3: Solve the equation for \( x \)
