Question

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

Answer 1

Alpha > beta>gamma

Step-by-step 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.

Answer 2

`\boxed {\boxed {\sf Gamma, beta, alpha}}`

Step-by-step explanation:

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

• Alpha particles are essentially helium ions, made of 2 protons and 2 neutrons. It has an atomic mass of 4 atomic mass units.

• Beta particles are also known as electrons. They have masses of 1/1840 atomic mass units.

• Gamma particles are actually just rays or photons of electronegative energy emitted. They have no mass or a mass of 0 atomic mass units.

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).
