A heavy element spliting into 2 or more lighter elements

Why do elements release mass in nuclear reactions to lose energy?

Mass can be transferred into energy using E=mc^2

Why do elements emit radiation?

Because they want to lose energy

Two elements coming together to form a heavier element

Answers

1
What is fission
A half-life occuring for an element
An element losing energy
A heavy element spliting into 2 or more lighter elements
Two elements coming together to form a heavier element
2
An alpha particles is
A short religious course
A helium nucleus
Helium balloon
A helium atom
3
Why do elements release mass in nuclear reactions to lose energy?
Mass can be transferred into energy using E=mc^2
Elements are stubborn like some people in this room
Energy is harder to release than mass
Losing mass stablizes more than losing energy
4
Why do elements emit radiation?
To stabalize the elements around them
Because they want to gain energy
Because they are mad
Because they want to lose energy
5

Gingervitis
Nuclear Fission
Chemical
Nuclear Fusion

Electron cloud
The lab
11
Which one is the fastest?
Alpha
Gamma
Beta minus
Beta plus
12
Which radioactive particle is the smallest?
Gluon
Positron
Gamma
Positive
13
How would the 1st half life and 3rd half life of an element compare?
They would be equal
It would be 1/3 as a great
It would be 3 times as great
Comparison is for unhappy people

Protons and electrons
All particles
Neutrons and electrons
15
What is half life?
The amount of an element left after it decays
The time needed for an element to stablize
Cutting an element in half to stablize
Time required for half of element to decay
16

Gambill
Beta
Alpha
Gamma
17
