Dear students, the lewis dot structure of nf3 gives the central atom nitrogen, how many bond pairs and how many non -bonding pairs.
00:10
This is our question.
00:12
So, let us draw the lewis structure of nf3, nitrogen, tri -fluoride.
00:19
Nitrogen has 5 electrons in its valent cell.
00:25
Its electronic confliction is 1 s2, 2 s2, 2p, 6.
00:32
6, it has 7 electrons, so it is 2p 3.
00:37
So that means here 2 electrons in 1 s, 2 s2 electrons and in p 3 unpaid electrons.
00:47
If you see fluorine has 9 electrons, so its electronic compression is 1 s2, 2 s2, 2p 5.
00:57
That means 1 s2 orbital arrangement is like this, then 2p 5.
01:04
So, here one unpaid electron is there...
