Question

when magnesium (mg2+) and fluorine (f1 -) combine in an ionic bond, the resulting formula will be a mg2f b mgf2 c mgf d mg2f2

Explanation:

Step1: Determine ion charges

Magnesium ion has a charge of +2 ($Mg^{2 + }$) and fluoride ion has a charge of - 1 ($F^{-}$).

Step2: Balance charges

To balance the charges in an ionic compound, we need 2 fluoride ions for every 1 magnesium ion.

Answer:

B. $MgF_{2}$
