M8 C16 - Properties of the Nucleus

Question 1

What is nuclear fission?

Answer 1

when a large nuclues splits into two smaller nuclei releasing enegry at the same time.

Question 2

how does fission occur?

Answer 2

when a lose neutron joins with a nuclues, turning it into an unstable nucleus. This will break down in multiple nuclei and release enrgy and lose electrons

Question 3

What is nuclear fusion?

Answer 3

when two smaller nuclei fuse to form a larger nucleus realsing enegry at the same time

Question 4

What are the 3 types of radio active decay

Answer 4

Alpha Decay
Bet Decay
Gamma Decay

Question 5

Briefly describe alpha decay

Answer 5

wheren an unstable atom’s nucelues relaease an alpha particle (2 protons & 2 neutrons) or heluim 4 nulceus

Question 6

Briefly describe Gamma decay

Answer 6

emits high energy photons from an excited nuclues without particle emission. deosnt chnage nuclues mass or charge

Question 6

Briefly describe Beta decay

Answer 6

**Occurs when the ratio of protons to neutoirns in the nuclues leads ot instability. **

• postive beta decay - proton tranforms itno a neutron, emits a positron & a nuetrino
• Negattive beta decay - nuetron tranfroms into a proton, emits a beta particle, and an antinuetrino

Question 7

What formula can be used to find enegry from nucelar reactions?

Answer 7

Question 8

Explain Half Life Decay

Answer 8

the time required fro a quanity to reduce to half its intial value., or called exponetial decay

Question 9

Recite the half life decay equations

Answer 9

N(t) = quantity remaining
N(i) = intial Quanity
Λ = decay constant
t = time elsaped

Question 10

whats the difference between fission and fusion?

Answer 10
