Answer 1

$\huge {\mathcal {\underline {\underline {\purple {AnSwEr}}}}}$

An uncharged particle found in the nucleus of an atom. A neutron, like a proton, contributes one atomic mass unit to the total atomic weight of an atom. Proton: A positively charged particle found in the nucleus of an atom

Answer 2

Answer:

The neutron is the uncharged particle found in the nucleus.

Explanation:

When Chadwick was researching extraordinarily penetrating radiation released by beryllium when struck with alpha particles in 1932, he found neutron.

The radiation emitted by beryllium was made up of a new, non-charged particle.

            $_4Be^{9} +_2He^{4}$ → $_6C^{12} +_0n^1$

The particle was given the name neutron by him. A neutron's mass is discovered to be $1.67*10^-^{24}g$ .

As a result, a neutron is a subatomic particle with the mass of a hydrogen ( $1.675*10^-^{24}g$ ) atom and no electrical charge.
