In this given question, we have to find incorrect option, incorrect option regarding formation of ionic bond.
00:19
Formation of ionic bond.
00:25
So what is ionic bond? ionic bond is that where the electron is transferred from the outermost cell from one atom and it is further accepted by the another atom.
00:34
For example, is sodium chloride nacl.
00:38
So na is alkali material, it have a valency of plus one whereas chlorine is halogen and it have valency of minus one.
00:55
So this plus one and minus one form an ionic bond with each other because sodium has one extra electron in its outermost cell or orbital that is 3s and whereas chlorine differentiate in 3p.
01:06
So it have a 3p, it have an electronic configuration of 3p5.
01:14
So it can accept one electron.
01:16
Whereas the alkali metal can easily donate one electron.
01:21
So they form an ionic bond with each other.
01:23
So we have to find which of the following statement are incorrect.
01:27
So the first statement says that the halogen form, halogen have a valency of minus one.
01:33
Correct.
01:34
Second says alkali metals have valency of plus one.
01:36
That is absolutely correct.
01:38
Okay.
01:39
And the other option says that the noble gases do not form ionic bond.
01:47
Noble gases do not form ionic bond...
