Latice energy is dependent on two factors, size of the given ion and charge on the given ion.
00:07
So we should always remember that side of iron.
00:15
So that is inversely proportional to lattice energy and charge on iron.
00:33
That is directly proportional to lattice energy.
00:46
So now in the first part we have c -a -o and c -a -s.
00:56
So in both the cases we have calcium ion, okay? so c -a -2 positive.
01:02
So since the charge is same, the ion is same, okay? so here the cat -ion will not be considered.
01:09
But we have oxide and sulfide in anions.
01:15
Okay, so that part is different here.
01:18
Okay, so now i hope you know that oxide and sulfide both belong to same group.
01:25
Okay, oxygen family...
