Which of the following forms of radiation particles has the greatest mass?

alpha particle

beta particle

neutron

gamma

The particle with the greatest mass is:

The alpha particle.

Explanation:

The mass of the Alpha Particle is considered to be 4 amu, which is the biggest of all these options.

The mass o the beta particle is considered to be 1/2000 amu which is considered to be the third place of the elements shown.

The neutron has a mass of 1 amu which makes it larger than the beta particle's mass and brings it to the second place of our rank.

The gamma particle mass is considered to be 0 because it is made of pure energy. Therefore it occupies the fourth place in our rank.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
