The atoms of different chemical elements can be differentiated based on the number of protons.
Each chemical element is differentiated by his number of protons. This number of protons is also knowing as atomic number and it is represented by the letter (Z).
The atomic number represented the number of protons in the nucleus of an element. For example:
- The element that has only 1 proton in his nucleus is Hydrogen atom.
- The element that has 2 protons in his nucleus is Helium atom.
The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.

Answer:
Coefficient in front of the in the balanced equation - 4
Explanation:
The unbalanced reaction is shown below as:-
On the left hand side,
There are 1 nitrogen atom and 3 hydrogen atoms and 3 oxygen atoms
On the right hand side,
There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms
Thus,
Right side, must be multiplied by 6 and
by 4
Left side, is multiplied by 5 and
by 4 so to balance the whole reaction.
Thus, the balanced reaction is:-
<u>Coefficient in front of the in the balanced equation - 4</u>
