Answer is valence electron, they all have total of 2 valence electron.
remember group number = valence electron
N₂ + 3H₂ ⇆ 2NH₃
↓ volume = ↑ pressure
The reaction shifts toward the product gas.

The Avogadro's number determines how many items make up a particular unit, such that 1 mole of a substance contains 6.022 × 10^23 items.
These items may be particles such as molecules, atoms, ions , etc
Therefore, 1 mole of anything has 6.022×10^23 items.
This number is called the Avogadro's constant and applies to all substances, and is normally used by researchers and scientists to determine the number of moles of elements and compounds.
I can’t see the equations
