Question

How many fluorine atoms bond with calcium to form calcium fluoride?

Answer 1

2 charge on calcium is 2+ and the charge on fluorideions is 1-. It therefore requires 2 fluoride ions to make the compound ..

Answer 2

Answer;

2 fluorine atoms

Step-by-step explanation;

• Calcium, a Group 2 metal, commonly forms a calcium ion (Ca2+). On the other hand, fluorine, a Group 7 non-metal, commonly forms a fluoride ion (F-). The necessity of electrical neutrality ensures that 2 Fluoride ions (F-) binds to one Ca2+
• The charge on calcium is 2+ and the charge on fluoride ions is 1-. It therefore requires 2 fluoride ions to make the compound electrically neutral.
