These diagrams show two atoms of fluorine and an atom of magnesium. On the left, a purple circle labeled F is shown twice, both times surrounded by 2 concentric circles. The inner circle has 2 small green spheres. The outer circle has 7 small green spheres. On the right, a purple circle labeled M g surrounded by 3 concentric circles. The inner circle has 2 small green spheres. The middle circle has 8 small green spheres. The outer circle has 1 small green sphere. Which shows the correct steps in the formation of an ionic bond between these atoms?
A magnesium atom accepts six electrons from the fluorine atoms β Each fluorine atom donates three of the electrons β The magnesium atom becomes a -2 ion β Each fluorine atom becomes a +1 ion
A magnesium atom donates two electrons to the fluorine atoms β Each fluorine atom accepts one of the electrons β The magnesium atom becomes a -2 ion β Each fluorine atom becomes a +1 ion
