Question

Calculate
number of valence
electrons in 4.2 g of
Ng ion.
2.1NA
4.2NA
1.6NA
3.2NA​

Answer 1

Explanation:

Each N3- ion has 8 valence electrons, so total number of valence electrons = 1.8 X 10^23 X 8 = 1.4 X 10^24 valence electrons

Answer 2

Answer:

Each N3- ion has 8 valence electrons, so total number of valence electrons = 1.8 X 10^23 X 8 = 1.4 X 10^24 valence electrons.
