The formula for calcium fluoride is
Calcium is an Alkaline Earth Metal in the second column of the periodic table. This means that calcium has 2 valence electrons it readily gives away in order to seek the stability of the octet. This makes calcium a
Fluorine is a Halogen in the 17th column or
Fluorine has 7 valence electrons. It needs one electron to make it stable at 8 electrons in its valence shells. This makes fluorine a
Ionic bonds form when the charges between the metal cation and non-metal anion are equal and opposite. This means that two
This makes the formula for calcium chloride,
I hope this is helpful.
