Question

valency of fluorine in calcium chloride by calculation

Answer 1

fluorine is not present in calcium chloride

Answer 2

heya!!
     
   May be u miswritten ur question. It have two probabilities :
1. Valency of fluorine in calcium floride
     In this case,  the formula of it is  Cafl2.
                              Now criss cross the numbers below, then 
                             so, calcium gets 2 and fluorine gets 1
                             therefore, the valency of calcium is 22 and valency 
                              of fluorine is 1
2.Valency of chlorine in calcium chloride
     In this case,  the formula of it is  Cacl2.
                              Now criss cross the numbers below, then 
                             so, calcium gets 2 and chlorine gets 1
                             therefore, the valency of calcium is 22 and valency 
                              of chorine is 1.
Its this simple:))

                                        Hope this helps ☺
                                        If yes, pls mark me as brainliest:)))
