Question

Which subatomic particles were discovered by?
A.Chadwick
B.Thomson
C.Goldstein

Answer 1

Hint: We have to know that a subatomic particle is a particle that is much smaller when compared to the size of an atom. We have to know when an atom is broken down three subatomic particles could be obtained. The three subatomic particles are neutrons, electrons, and protons.

Complete answer:
Let us now discuss the three types of subatomic particles.
Protons: The positively charged subatomic particles are protons. In an atom, the number of protons and number of electrons are equal. When an electron is removed from an atom of hydrogen, protons could be formed. Protons are found in the nucleus of an atom. $1.676 \times {10^{ - 24}}grams$ is the mass of a proton. $ + 1.602 \times {10^{ - 19}}Coulombs$ is the charge of a proton.
Electrons: The subatomic particles that rotate around the atomic nucleus. Ions are formed when an atom gains (or) removes electrons. In chemical bonds, electrons of several atoms come together to take part. These subatomic particles are negatively charged particles. $ - 1.602 \times {10^{ - 19}}Coulombs$ is the charge of an electron.
Neutrons: These subatomic particles are found along with protons in the nucleus. We can call protons and neutrons as nucleons on the whole. These subatomic particles are neutral charge (or) do not possess any charge. $1.676 \times {10^{ - 24}}grams$ is the mass of a neutron.
A.Neutrons were discovered by James Chadwick.
B.Electrons were discovered by J.J. Thomson.
C.Protons were discovered by Eugen Goldstein.

Note:
We have to know that the smallest subatomic particles are Quarks. We have to know that subatomic particles are much smaller when compared to atomic size of an atom. The subatomic particles protons and neutrons contribute to the mass of atoms. The electrons contribute to the total volume of atoms. We can determine the atomic number of an element by using the protons. We can determine the isotope of an atom by using the neutrons.
