Question

calculate the no. of electrons present in one mole of N3- ion​

Answer 1

Answer:Nitrogen originally has 7 electrons in the valence shell. But bcz there is a -ve 3 charge on the nitrogen atom, the number of electrons is increased and now count to 10 electrons per azide ion. Now, we know that the number of atoms in one mole of a element is 6.023*1023

Answer 2

N3- is there

So, =Nitrogen Atomic Number + 3

      =7+3

      =10

= 6.023*1023 give (?) electron

= 6.022*1023*10

= 6.022*1024

Hope you Understood !!!
