Chemistry: The study of radioactivity and nuclear reactions

What strcuture is similar to a beta plus particle

It is similar to the same as a particle of antimatter

When two hydrogen nuclei combine together, what occurs?

A fusion reaction occurs

What does a fission reaction require?

a light atomic nuclei and extremly high temperatures

What ocurs in a controlled fission?

Neutron bombardent splits heavy nuclei

What particle has the lowest penetrating particle?

Alpha particle has the lowest penetrating power and is also able to be blocked by a human hand or a sheet of paper.

What are nuclear reactions?

when two nuclei or a nucleus and another particle, collide to product or more nucleides

What is fission?

process of splitting a nucleus into smaller fragments by bombarding neutronsto release a large amount of energy.

What is fusion?

process of combining two or more nuclei to produce a single, heavier nucleus

-extreme high temperatures

occurs naturally on the suns surfaceand requires extremely high pressures.

What is Radioactivity?

is when an unstable nucleus loses energy by radiation

-radiation can be pure energy or particles

-stability is primarily determined by the ration of neturons/protons

Alpha Decay Particle( Characteristics)

creates alpha particles

-nucleus releases 2p+ and 2n0 as a new helium nucleus 42He

Beta Decay ( Characteristics)

creates beta particles

-nuetron splits into a proton and an electron

Beta Plus ( Characteristics)

Proton splits into a neutron and an positron

• positron is a positive electron that is emitted from the nucleus

Gamma Decay ( Characteristics)

creates gamma radition

-can occur after an alpha or beta decay

-pure energy, so no mass or charge
