The orbit of an electron around an atomic nucleus is in some ways comparable to that of a satellite (such as the moon) around a planet (such as the Earth) although it is also very different, in some other ways. Why does the moon not crash into the Earth? Because it has a certain amount of angular momentum which keeps it in orbit (although not forever; given enough billions of years, eventually the moon will crash into the Earth). Electrons also have energy, which is similar to the momentum of an orbiting satellite, which keeps them in orbit, so that they don't just crash into the nucleus. But that too is not an absolute; there are some circumstances in which the electron does fall out of orbit and collide with the nucleus, in which case it combines with a proton forming a neutron (which is a form of radioactive decay, transforming the atom into a different element). As electrons gain energy (by absorbing photons) they move into higher orbits; when they lose energy (by emitting photons) the fall into lower orbits.

Why electron does not fall in nucleus to attack towards proton?

Is there any force acting on an electron?
The answer simply depends on the environment that the electron is in. If the electron is in orbit around the nucleus of an atom then there will be a strong electromagnetic force acting on the electron towards the nucleus.
What does the nucleus of one atom want to do to the electrons of a nearby atom?
If the nucleus is missing an atom, it will try to steel an electron from another atom.
Why does elctronegativity decrease as you go down a group on the periodic table?
the electron affinity decreases down the group because new electrons continuously add in a outer shells that are far away from nucleus,so these electrons are less attracted to the nucleus and that's why releases less energy when added
Why is usually only one electron removed from an atom?
An electron has several shells with electron. When these shells are completely filled, the most outer shell doesnt relatively feel much attraction of the electrons towards the nucleus. Therefore it is possible that one electron gets out of the shells. If this is done, the atom has too little amount of electrons, it needs one more. The attraction force is then increased, which means it takes a lot of more energy to remove the second electron, let alone the third

What does an electron do for an atom?
absolutely nothing all it does is be drawn towards the nucleus

When a atom losses a electron it becomes what kind of ion?
A cation. A positively charged ion that is attracted towards the cathode in an electrolytic cell.
Why are electrons attracted to the center of the atom?
Electrons are attracted to the center of the atom, called the nucleus, due to the positively charged protons in the nucleus. Opposite charges attract, so the negatively charged electrons are drawn towards the positively charged nucleus. This attraction keeps the electrons orbiting the nucleus in defined energy levels.
The outer electaons are attracted to the nucleus by a force stronger than the inner shell eclectrons?
No. The outer shell (valence) electrons are not attracted towards the nucleus as strongly as are the inner (core) electrons. This is why they could be traded in and out during chemical reactions, while the core electrons normally could not.
Why electrons move in electricity?
Electrons will move in response to an electric potential - also known as a voltage. The electron will be attracted towards, or repelled from, one direction, due to this voltage.
Why is it easier to remove an electron from bromine then it is to remove an electron from fluorine?
The reason why fluorine has a higher ionization energy level than oxygen is because it is closer to the nucleus than is oxygen, therefore, it will take more energy to pull electrons from the nucleus.
Why are beta particle is attracted to the positive electric field?
Beta particles are electrons that have been emitted from the nucleus during beta decay. As negatively charged particles, they are attracted to positively charged electric fields due to the fundamental principle of opposite charges attracting each other. This attraction causes the beta particles to move towards the positive electric field.
What happens to the electron as it moves closer to the nucleus?
An electron moving towards the nucleus slows down and any energy it contains from a higher shelf is released.
What does the nucleus of one atom want to do to the electrons of a nearby atom?
If the nucleus is missing an atom, it will try to steel an electron from another atom.
Why do electrons keep moving around the nucleus of the atom and not fly away?
Since the electrons are negatively charged and the nucleus is positively charged due to presence of protons, they attracted towards each other by the electrostatic force of attraction and thus electrons keep revolving around the nucleus and do not run away
