Geiger Counter to measure radiation

Background radiation is everywhere

Neon 10 protons and 10 neutrons

Calcium is equal

Sn decrease in protons

Nucleons are held by a strong force

Uranium has 92 protons

Protons fall apart without a strong force

126 would be the perfect amount

radiation is parts of atoms that are given off

measure by using a geiger camera

there’s always background radiation everywhere

as you move up the periodic table the number of protons decreases compared to the number of neutrons

type of decay: beta minus, beta plus, alpha decay, fission

particles were being drawn in different directions : alphas decay has a positive charge so it’s drawn towards the negative

beta decay has a negative charge so it goes to the positive

alpha decay is helium, weak : beta decay is an electron

Radioactivity is measured by Geiger counter

More neutrons than protons as the periodic table increases

Elements give off to reach the perfect ratio of protons to neutrons

Alpha decay has a positive charge

Beta decay has a negative charge

Alpha decay is 2 protons and 2 neutrons (helium)

Beta decay is 1 electron

Gamma radiation has no charge

nucleus held together by strong nuclear force

different types of decay:

alpha decay has positive charge

beta decay has negative charge

Alpha decay is 2 protons and 2 neutrons no electrons - Helium

Gamma radiation, lots of energy

Uranium-> alpha decay, looses helium nucleus. 2 protons lost, then becomes thorium

Measure radiation by Geiger counter

Initial static comes from background radiation

Alpha decay is 2 protons and 2 neutrons

Alpha decay is weak

Gamma radiation occurs when there is a strong nuclear force

Soil or led is how to stop gamma radiation

Nucleus is held together by the strong nuclear force.

If an atom exists on either side of the perfect line, they will give off protons/neutrons to get back on the line.

All types of radiation are ways for an atom to get back to the perfect ratio of protons-neutrons.

If we allow radioactive material to shoot through a tunnel, you get radiation to show up on the other side.

Alpha decay is weak and can’t even move through a piece of paper.

Beta decay has no mass.

When nucleons wiggle, their energy is given off in the form of gamma radiation.

Geiger sounds static because of background radiation

Using the Geiger, you can find how old the earth is

Protons decrease and neutrons increase

They want to separate because of the positive charges (protons)

But if there is something with a lot of protons, you need something to hold it together

Beta minus decay is on the left side, beta plus decay is on the right, alpha (positive charges) is on the top side of the graph

Gamma decay is when energy gives off as gamma radiation

In alpha decay, Uranium would lose two protons and 4 mass units. 90 protons left, it would no longer be uranium

Number of protons each atom contains in atomic number

Every atom born in fire

114 is non existent

Creating 114 is an act of creation not discovery

92 is last of the naturally occurring elements

Seborg created my adding in 1 new nucleus’s at a time

Nuclear force is the strong force
