density= mass/volume
we need the volume of the metal to find the density, in which case the answer would be 64.2/volume=density

It would be A) Cl, K, Ar
Because Cl=35,K=39,Ar=40
There is 1 H atom: (1)(+1) = +1 The oxidation number of O is -2. There are 4 O atoms here: (4)(-2) = -8 So the oxidation state of Cl is +7.
NOTE: The maximum positive oxidation number for chlorine is +7,<span> the same as its group number (VII).</span>
