1. compare and contrast the processes of nuclear fission and fusion, showing similarities and differences. describe which, if any, of these processes is naturally occurring. if so, where?

2. what is the half-life of sodium-24? sodium-24 decays by beta emission. write a nuclear equation that shows the decay of sodium-24 and its products.

3. describe the subatomic structure of the nucleus, including the structure of each nucleon. describe the forces that hold the nucleus together and draw them on your diagram.
explain how beta emission works.

Step-by-step explanation:

1. Nuclear fission is a process of conversion of a nuclear mass into energy. If we have an unstable isotope bombarded by a neutron, then it splits into some other elements with a chain reaction, producing energy.

Scheme:

Nuclear fusion is a process of union (fusion) of atomic nuclei combining them into one with heavier mass releasing huge amounts of energy.

Scheme:

Nuclear fission occurs in nature, although rarely. A classical example is the uranium fission, found out in Gabon, Africa.

2) According to modern spectometry the half life of Na 24 is ≈15h.

3) There are more than 200 subatomic kinds of subatomic particles. There are 4 classes of subatomic particles: Quarks, Leptons, Gauge Bosons and Scalar bosons.

In the Nucleus there are protons and neutrons, and the electrons draw an elliptical curve. All these particles are held together by electrical charge.

A beta emission works either negative or positive, it is an emitted by a high speed electron or by a positron.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
