1.	The total no of valence electrons in 4.2 g of N3- ion is
Answer» Answer: Explanation: Moles of N−3 ION =4.242=0.1 Each nitrogen atom has 5 valence electrons. Therefore, TOTAL number of electrons in N−3 ion =16 Total number of electrons in 0.1 MOLE or 4.2 g of N−3ion=0.1×16×NA =1.6NA Thank you

Answer:

Explanation:

Moles of N−3 ION =4.242=0.1

Each nitrogen atom has 5 valence electrons.

Therefore, TOTAL number of electrons in N−3 ion =16

Total number of electrons in 0.1 MOLE or

4.2 g of N−3ion=0.1×16×NA

=1.6NA

Thank you
