Fluorine gas is placed in contact with calcium metal at

When fluorine gas reacts with calcium metal at high temperatures then it results into the formation of calcium fluoride. Since, calcium has 2 extra electrons as its electronic distribution is 2, 8, 8, 2. Whereas each fluorine atom needs one electron to complete its octet. Therefore, the chemical reaction equation will be as follows.
