The nucleus
Electrons do not crash into the nucleus because they are constantly in motion and are held in orbit around the nucleus by the electromagnetic force. This force keeps the electrons at a certain distance from the nucleus, preventing them from colliding with it.
plates keep earth in motion
The force that keeps an object in motion stay in motion is called inertia. Inertia is the tendency of an object to resist changes in its velocity.
Any body in the universe is never said to be rest as the electrons inside it keeps moving to and fro and thus no matter on the universe is in standard rest.
Envy
The electrons can be in motion. These are present outside the nucleus.
In metals electrons are in a permanent motion.
Electrons are subatomic particles. Since electrons exhibit wavelike repeated motion, they tend to follow the same path around an atom.
just like earth's revolution around sun , the cinterfigural force and the centerpetal force , however the center seeking force is due to electromagnatic attraction.
The centripetal force
Chemical reactions
Electrons move around the nucleus due to the attractive force between the positively charged protons in the nucleus and the negatively charged electrons. This force, called electrostatic attraction, keeps the electrons in orbit around the nucleus.
