Why don’t all of the particles in an atom contribute to the mass?
kotegsom [21]

Answer:

Explanation:

The mass of an atom is dependent on its number of protons and neutrons. Electrons have mass, but are too light in comparison to protons and neutrons to contribute towards the overall mass. Their relative mass is about 1/1840 compared to 1 for protons and neutrons, and therefore are not counted in the mass.

Hope this helped!

nadezda [96]

Superscript o subscript negative 1 e.

Explanation:

The nuclear reactions is of 2 types, one is nuclear fusion and the other one is nuclear fission.

Nuclear fusion is nothing but the combining of 2 nuclei with an emission of energy along with an electron, proton or beta particle.

Nuclear fission is the break down of a nucleus into 2 or more nuclei along with an electron, proton or beta particle.

And the reaction is,

₅₆B¹²⁴  ₅₅C¹²⁴ +  ₋₁e⁰

So the blank was filled by means of a beta particle.
