Radiation Quiz

Which radiation does an atom need to emit to change its nucleus?

What are the Three Types of Radioactivity called?

Sometimes the [blank_start]nucleus[blank_end] of an atom is un[blank_start]stable.[blank_end] A change will occur in the [blank_start]nucleus[blank_end] to make it more stable. The change is called a [blank_start]decay[blank_end]. When a nucleus decays it will emit (give out) some [blank_start]particles[blank_end] or waves.

[blank_start]Alpha[blank_end] particles do the most damage because they are the heaviest and they carry a positive charge

When the [blank_start]nucleus[blank_end] of an atom possesses either too many or too few [blank_start]neutrons[blank_end] compared to the number of protons it becomes [blank_start]unstable[blank_end]. These are called [blank_start]radioactive isotopes[blank_end]. Unstable nuclei split up in a process called radioactive [blank_start]decay[blank_end] and emit radioactive radiation.

What does the Nucleus of an Atom contain?

Why do Gamma Rays and Beta particles penetrate further than Alpha?

What is the Atomic Number?

What is the mass number

Isotopes are the atoms of an element with different numbers of [blank_start]neutrons[blank_end]. They have the same [blank_start]proton[blank_end] number, but different [blank_start]mass[blank_end] numbers.

Alpha is positive Beta has no charge Gamma is negative

Why do Alpha particles cause the most damage?

How can a Nucleus be Unstable?

An Alpha particle is made of ___________ and____________,like the element_____________.

Does an Alpha Particle have More Mass than a Beta Particle?

Does an Alpha Particle have More Penetrating Ability than a Beta Particle?

Is an Alpha Particle More Ionising than a Gamma Ray?

After a radioactive [blank_start]nucleus[blank_end] has emitted an [blank_start]alpha[blank_end] particle, the [blank_start]mass[blank_end] number goes down by 4 and the [blank_start]atomic[blank_end] number goes down by 2.This change in the [blank_start]atomic number[blank_end] produces a different [blank_start]element.[blank_end]

[blank_start]Alpha[blank_end] radiation is not as dangerous because it is unlikely to reach living [blank_start]cells[blank_end] inside the body. [blank_start]Beta[blank_end] and [blank_start]Gamma[blank_end] radiation are the most dangerous sources because they can [blank_start]penetrate[blank_end] the skin and damage the cells inside.
