The given problem is metal plus non -metal, metal plus non -metal, will give ionic product, will give, sorry, ionic bond.
00:35
First, metal is equal to electropositive element.
00:41
Metal is equal to electropositive, positive element.
00:52
I first group of element first group element is equal to lithium sodium potassium ribidium and cesium li n a potassium rbidium and c s and the second a group second a group elements is equal to bemg, tasr and b .a.
01:51
Number second, non -metal is equal to electrone negative element.
02:00
Non -metal is equal to electronegative element.
02:21
So seventh a group, seventh a group elements.
02:31
7th group elements is non -metal elements.
02:38
So this is fluorine, chlorine, bromine and iodine, oxygen, sulfur, nitrogen, etc.
02:53
Electropositive plus electronegative is equal to ionic bond.
02:56
Electropositive plus electronegative is equals to ionic bond.
03:15
So here, sodium electropositive plus iodine electronegative.
03:29
Sodium, sodium plus iodine gives n .i...
