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?
The chemical formula for the product of the reaction when beryllium and fluorine combine is BeF2. This is because beryllium has a valence of +2, meaning it can give away 2 electrons, and fluorine has a valence of -1, meaning it can gain 1 electron. Therefore, one beryllium atom can combine with two fluorine atoms to form BeF2.
