Question

The total number of valence electrons in 4.2 grams of nitride ion are​

Answer 1

Answer:

mark as brainliest answer.

Explanation:

→ Mole of Nitrogen is 4.2/14=0.3. and valance electron of Nitride is 8 Because it has 10 electrons so electrons are like this (2,8).

Answer 2

Answer:

2.4 N  

Explanation:

Number of valence electrons=(given weight)/(atomic weight)*10*N

Mole of Nitrogen is 4.2/14=0.3. and valance electron of Nitride is 8 Because it has 10 electrons so electrons are like this (2,8).
