Answer:
            3 electrons are gained by one nitrogen atom in the formation of K₃N.

Explanation:

The reaction is as follow,

<span>                                       6 K + N</span>₂<span>    </span>→   <span> 2 K</span>₃<span>N
</span>
Oxidation of K,

                                       K     →     K⁺  +  1 e⁻
Or,
                                    6 K     →    6 K⁺  +  6 e⁻

In oxidation reaction potassium atom transfers one electron per atomn and six electrons per six atoms.

Reduction of N;
                                  N₂  +  6 e⁻    →    2 N³⁻

In reduction reaction one molecule of N₂ gains six electrons and 3 electrons per one atom

In alpha and beta decay the parent element and the daughter element can be
Angelina_Jolie [31]
In alpha and beta decay the parent element and the daughter element will be different isotope and not the same. 
This is because as alpha particles comes out; the new element will have two less in atomic number; that is the atomic number will reduce by two and the mass number will reduce by four. While in a beta particle decay, the new element will have one higher in atomic number; that is the atomic number will increase by one.

Atoms of different chemical elements can be differentiated based on the number of.
Alona [7]

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.

<h3>What is an atom?</h3>

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.
