Hello and welcome to Dendron's first
video! Let's start. Now, before answering
the question of how atoms stay together,
we first have to get some background.
There are four fundamental forces which
govern our universe. They are: gravity,
electromagnetism, the Strong Force, and the
Weak Force. I won't go into much detail
about gravity and the Weak Force. First
of all, is electromagnetism.
This force is what attracts electrons to
protons. It is the reason why opposite
charges attract and same charges repel.
The electromagnetic force covers a part
of how atoms stay together, and the
Strong Force is responsible for the rest.
The Strong Interaction is the most
powerful fundamental
force. It is so powerful, in fact, that
it is 100 times stronger than
electromagnetism. This allows the strong
force to completely negate the "same
charges repel" rule.
When put simply, how this works has to do
with the much smaller elementary
particles which make up protons and
neutrons. Among these particles, the
Strong Interaction particularly affects
quarks.
