Beryllium (Be) has four electrons. Fluorine (F) has nine electrons. Which chemical formula shows the correct subscripts for the product of the reaction when beryllium and fluorine combine?(1 point)ResponsesBeF2BeF 2Be2FBe 2 FBeFBeFBe2F2

Answer 1

When beryllium (Be) and fluorine (F) combine, they form an ionic compound. Beryllium has a valence of +2, and each fluorine atom has a valence of -1. To balance the charges, we need two fluorine atoms for every one beryllium atom.

Thus, the correct chemical formula for the product of the reaction when beryllium and fluorine combine is BeF2.
