Atoms + Periodic Table
What subatomic particle is positive?
proton
What are the 3 types of radiation?
Alpha, beta, gamma
When writing a Chemical Reaction, what goes on the right of the arrow?
The Products
(The reactants go on the left)
List the types of decay in order of penetrating power (greatest to least).
Gamma, beta, alpha
What is the name of Harry Potter’s pet owl?
Hedwig
What subatomic particle is neutral?
neutron
What changes about an atom if it is only undergoing gamma decay?
Nothing. Gamma rays have no charge or mass.
What is the "Law of the Conservation of Mass?"
In a chemical reaction nothing is created or destroyed
Name a Safety Measure when dealing with Radioactive treatments.
Lead (PPE)
Distance
Time
Safe Disposal
What is the capital city of Spain?
Madrid
What is the group name of the elements in Group 8 of the Periodic Table?
Noble Gases
What is the atomic number of the new isotope produced after radon undergoes alpha decay?
84 - Polonium
C6H12O6+6O2→6CO2+6H2O
What are the Reactants in this reaction?
C6H12O6 and O2
Explain why Lead is used as a safety measure in radioactive medicine.
Name a animated Disney Movie which was based on a real-life person.
Pocahontas
Mulan
What element has an atomic mass of 51 and a neutron number of 28?
Vanadium (V)
What two things are produced if carbon-14 undergoes beta decay?
Nitrogen-14 and an electron
Why do Equations need to be balanced?
Because the same number of atoms need to be present on each side of the equation. Nothing is created or destroyed in chemical reactions just rearranged.
Why is "Informed Consent" an Ethical consideration and how has it influenced research when dealing with radioactive medicine?
Informed consent ensures patients understand the treatment, risks involved and any alternate options available to them.
Not having this completed means the patient does not have authority over what happens to their body.
What is
(5 x 2) 2 + 64
164
What element is in Group 4 Period 3?
Silicon (Si)
A radioactive substance has a half-life of 4 hours. If you start with 80 grams, how much will remain after 12 hours?
10g
Number of half-lives = 12 ÷ 4 = 3
After 1st half-life (4 hours): 80 ÷ 2 = 40 g
After 2nd half-life (8 hours): 40 ÷ 2 = 20 g
After 3rd half-life (12 hours): 20 ÷ 2 = 10 g
Balance this Equation
N2+H2→NH3
N2+3H2→2NH3
Why is disposal of radioactive waste a safety, environmental and ethical issue?
Radioactive waste can sometimes take years to decay meaning the waste could be radioactive for a long time. This means it will need to be stored correctly so to not damage waterways for a long time as well as people or animals nearby.
Who won the Superbowl in 2025?
Philadelphia Eagles
