How is it possible to create a stable nucleaus by all these protons when they repel?
Because there are four forces in nature. One imp force is very small 10^-15.
Strong nuclear force is responsible for the stablility of the nuclei
-When you heat atoms up, they move faster.
-Fusion is joining to two lighter elements to heavy elements.
-Fission is taking up a heavy nuclear and breaking it up.( but can’t go heavier than IRON
otherwise the sign changes to negative (-))
-You weigh differently on mountains
-Difference in mass is called mass defect
-Darkest lines was A
-Second strongest lines B
-Lightest line was O
A0- A10 B0-B10
Our sun is a G star, (G2 star)
