Nuclear Chemistry Quiz

Chemistry Unit 3

What is a nucleon ratio?

a ratio of protons to neutrons

How do neutrons help the atom?

they act as a glue and keep it stable

When is an atom considered unstable?

if the nucleon is greater than 1:1.5

What is the last non-radioactive element on the periodic table?

#82

What is chemical stability?

how resistant an element is when undergoing a chemical change (the electrons)

What is nuclear stability?

how likely a nucleas is to stay intact and resist decay (the protons and neutrons)

Alpha Particles

essentially a helium

Beta Particles

an electron

Gamma particle

like a photon or ray

What is nuclear bombardment?

a manmade chemical reaction that essentially shoots a particle at a pre-existing nucleas

Neutron

energy released

What does a Geiger counter do?

Measures radiation

What is nuclear fusion?

Combining two small massed elements

Pros to nuclear fusion

-low waste

-clean energy

-produces more energy

Cons to nuclear fusion

-really complicated

-really hard to do

What is nuclear fission?

Splitting large massed elements to collect their energy

Pros to nuclear fission

-easy

-efficient

Cons to nuclear fission

-produces lots of waste

-produces less energy

Where does nuclear fission occur?

In the dome building of a nuclear fission plant

How much U-235 is in a nuclear fission plant?

less than 1% of what was in the atomic bomb

What produces the energy in a nuclear fission plant?

the small controlled reaction creates steam which is converted to energy

T/F the smoke stack emits smoke in a nuclear fission plant?

False

How is steam converted to energy?

Through turbines and generators
