What are the two types of reactions that all nuclear reactions undergo?

fusion and fission

Where was Maria Sklodowska born and raised?

Poland

100
The type of decay that can be stopped by a piece of paper
alpha

Thorium 236 decays into Thorium 232. What type of radiation occurred?
apha decay, loses two protons and two neutrons (a weight of 4) 236-4=232
200

the emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei

What is Radioactivity?

200

What is the missing piece of this Nuclear Equation?

3516S  --> __?__ + 3517Cl

0-1e   AKA a beta particle

200

Why did Marie struggle to get an education?

Because she was poor and a woman - women were not commonly allowed in Universities during this time. Especially in Poland. 

200
The type of decay that can be stopped by aluminum/steel
beta decay

If an element undergoes beta decay will the atomic mass change? Explain how it will change...

Technically yes... but a beta particle has a miniscule mass. Therefore, a particle undergoing beta decay will NOT show a change in mass in its isotope notation.

Nuclear Chemistry is famously used for...

Any of the following are acceptable:

medicine, bombs, energy, electricity, power

300

What is the missing piece of this Nuclear Equation?

238 92U -->  __?___ + 234 90Th

42He   AKA an alpha particle

How many Noble Prizes did Marie Curie win? What subjects were each of her prizes in?

She won TWO Noble Prizes

1st Prize - Physics (she won this prize with her husband Pierre)

2nd Prize - Chemistry (for the discovery of Radium and Polonium)

The type of decay that can be stopped by lead
gamma decay
300
Carbon 18 loses two protons and two neutrons, it has gone through __________ decay
alpha decay
400
True or False. There is radiation all around is but it is low enough to be safe.
True it is called background radiation

The half-life of cobalt-60 is 5.26 years. If 50 grams are left after 15.78 years, how many grams were in the original sample?

400 grams

400

DOUBLE JEOPARDY (if you can answer BOTH parts...)

1) What did Marie Curie die of?

2) WHY is radium so dangerous? (think of the disease Marie Curie died of and the Radium Girls...)

1) Bone marrow disease/ lymphoma

2) Because Radium mimics Calcium and is easily absorbed into the bones. 

400
The type of decay where two protons and two neutrons are lost
alpha decay
400
If uranium 267 undergoes gamma decay what does it become?
Uranium 267 because gamma decay loses no mass or matter just energy
500
the time it takes an amount of radioactive material to lose half its radioactive atoms
half life

The half-life of plutonium-239 is 24,300 years. If a nuclear bomb released 8 kg of this isotope, how many years would pass before the amount is reduced to 1 kg?

72,900 years

500

The test tubes/ samples of Radium that occupied Marie and Pierre Curie's lab are said to have "____________" at night. 

"Glowed like earthly stars" due to its radioactivity properties. 

500
The type of decay where waves of energy are lost
gamma decay
