is a negatively charged particle

Beta particle
b.Gamma particle
c.Alpha particle

a. Beta particle

a. Beta particle

A beta particle is a negatively charged particle. It is an electron or a positron emitted from the nucleus during radioactive decay. Beta particles have a charge of -1, and they are much smaller in mass compared to an alpha particle.

A negatively charged particle is a beta particle.

To arrive at this answer, we can examine the three options provided:

a. Gamma particle: Gamma particles are not charged particles. They are actually high-energy photons or electromagnetic radiation.

b. Beta particle: Beta particles are charged particles with a negative charge. They are essentially high-energy electrons or positrons that are emitted during certain types of radioactive decay.

c. Alpha particle: Alpha particles are charged particles, but they have a positive charge. They consist of two protons and two neutrons, so they are essentially the same as helium nuclei.

Therefore, out of the options given, the negatively charged particle is a beta particle.
