Respuesta :

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 fluorine atoms

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.
