Introduction to Nuclear Chem Part 1

What is a common misconception about radioactivity?

• It has no effect on the environment.

• It only mutates genes.

• It can be used to generate electricity.

• It is completely safe.

What do we call when the protons and neutrons interact in chemical reactions releasing far more energy then when electrons get involved?

• Nuclear bombs

• Nuclear Chemistry

• Alchemy

• Magic

What happens when you change the number of protons in any atom?

• Nothing happens

• You get an ion

• You get an isotope

• You get a different element altogether

What types of elements do we get when we change the number of neutrons in an atom?

• Ions

• Neutral elements

• Isotopes

• alchemy

What is RADIOACTIVE DECAY?

• when a nucleus of an atom decomposes to form a more stable one

• releasing of electrons from an element

• magically turning lead into gold

• regular, everyday chemical reactions

What happens when the nucleus of an atom changes?

• The atom becomes more stable.

• The atom's identity changes.

• The atom loses all its electrons.

• The atom becomes a gas.

What is the term for changing one element into another?

• Transmutation

• Transformation

• Transfiguration

• Translocation

What are the three most common types of radioactive decay? (select 3)

• alpha

• omega

• gamma

• beta

• neutral

Which type of decay releases an alpha particle?

• Beta decay

• Gamma decay

• Spontaneous fission

• Alpha decay

What is unique about gamma decay compared to other types?

• It releases a particle.

• It is the slowest type of decay.

• It releases only energy.

• It changes the element.
