Why do electrons keep moving around the nucleus and not away from the atom

We know that the nucleus has a net positive charge from the presence of protons. Therefore, the nucleus has an attractive force on anything negatively charged, such as an electron. Much like a satellite orbiting a planet, if the electron has the correct velocity (potential energy), it will orbit the nucleus.
There is a problem with the orbit, though. The amount of energy possessed by the electron determines its energy state, and so the electron may not orbit in exactly a circular orbit. With more energy, the path may become dumbbell-shaped. With enough energy, the atom can potentially ionize--the electron escapes and leaves the atom with a net change in charge.
So the answer is both--electrons in a low energy state will orbit an atomic nucleus to balance charge, and electrons with a high enough energy can escape an atom.

because they like the neutrons hahahaha
it is because electrons are negatively charged and neutrons are positively charged so they attract each other du to which electrons dont move away from the neutron
u can say they are girlfriend and boyfriend and when an atom forms a bond it is like electron finds a new girlfriend

Electrons are bound to the nucleus by Electrostatic force(Coulumbian force), this is due toi positive charge of proton.
This provides an centripetal force, this force changes only its direction constantly without alktering its velocity.

opposite charges attract each other. electron is a negative charge. there are protons in a nucleus, and hence the nucleus is positively charged.

You know that protons are positively charge and electrons are negetively charged.Therefore, they attract each other.
Also there mass is more which increases it's gravitational pull(Newton's law of gravitation).so electron move at at a very high speed(centrifugal force) so that they don't collide and destroyed.

Because of coulombs law, opposite charges attract. They are attracted to the protons
