Transcript

00:01 Dear students, question is consider the nitrate ion.

00:04 The question is on nitrate ion.

00:05 The first question is how many valence electrons does one electron, one nitrogen atom have? we know nitrogen is having total 7 electrons to 5.

00:18 So first cell contains 2 electrons, second cell contains or the outer most cell contains 5 electrons.

00:23 Therefore number of valence electrons equal to 5 in nitrogen.

00:28 Next one how many valence electrons do 3 oxygen atoms have? we know oxygen has atomic number 8.

00:35 So 2, 6 each oxygen is having 6 valence electrons.

00:39 So 6 multiplied by 3, 18 valence electrons 3 oxygen atoms have.

00:44 Next is how many valence electrons does 1 no3 minus ion have? no3 minus ion have nitrogen, 1 nitrogen and 3 oxygen atoms and 1 unit of minus charge.

00:56 So 1 nitrogen atom is having 5, 3 oxygen atoms 18 plus 1 electron for minus charge.

01:04 So 19 plus 5, 24.

01:07 Next question is draw a valid leave structure for no3 minus ion below.

01:12 We will draw a valid leave structure nitrogen double bond o minus here one oxygen.

01:31 Let us draw again once again nitrogen double bond minus charge here.

01:48 So this is a valid leave structure because all atoms are having their complete uptakes.

01:55 Can you draw equivalent resonance structure for this ion? if so indicate this below.

02:03 So let us write the equivalent resonance structure for this nitrate ion.

02:07 So the resonance structures are can write here o like this...
