{N_A}

is Avogadro’s number, then number of valence electrons in 4.2 g of nitride ions (

{N^{3 - }}

) is

View answer and explanation

Correct option: A

2.4\,{N_A}\,

Option A (

2.4\,{N_A}\,

) is correct because the number of valence electrons in 4.2 g of nitride ions is calculated based on Avogadro's number and the number of valence electrons per ion.
