I.

When first discovered, α, β and γ radioactivity were referred to as α-rays, βrays and γ-rays. Now we refer to α-particles and β-particles, but still use the
term γ-rays. What type of particles are α and β commonly known as? What is γ commonly known as?

II.

What is the mass (calculate both in kg and unified mass units, u) of the α -
particle? What is the mass (calculate both in kg and unified mass units, u) of
the β -particle? Which particle (α or β) is more massive? Which particle has a
greater amount of charge (α or β)? Which particle (α or β) would you expect to
penetrate further into a piece of lead?

Expert Answer

Step 1

Since we are entitled to answer one question per request. We would be answering the first question. If you need help with other questions, kindly repost the question and put up a new request.

Step 2

An unstable heavy nucleus spontaneously emits energy in the form of radiations. This phenomenon is known as radioactivity.

There are three types of radiation emitted by the heavy nucleus:

Alpha particle

Beta particle

Gamma rays

Step 3

Alpha particle is radiated by nucleus of heavy mass. Alpha particle is the Helium nucleus and it has 2 protons and 2 neutrons. Electrons are absent in alpha particle. So, it is also referred to positively charged radiation. Alpha particles are commonly known as Helium nucleus.

Beta particles are generally emitted by the nucleus having more numb...
