Can u guys help on 22. It will only take a min.

Alpha > beta>gamma

Explanation:

Comparing only the three common types of ionizing radiation, alpha particles have the greatest mass. Alpha particles have approximately four times the mass of a proton or neutron and approximately 8,000 times the mass of a beta particle.

Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.

Explanation:

Alpha. beta, and gamma particles are all emitted from an unstable or radioactive nucleus during radioactive decay.

So, if we place the mass in increasing order (least to greatest), then it is gamma (0 amu), beta (1/1840 amu) and alpha (4 amu).

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
