I am not quite sure what you mean with "not connected"; the electron is attracted, via the electrical force, to the nucleus. This is the "connection" that keeps it there - as long as there is no stronger force to pull it away.
Electrons surround the nucleus of an atom due to the attraction between the positive charge of the protons in the nucleus and the negative charge of the electrons. This electrostatic force of attraction keeps the electrons in orbit around the nucleus, maintaining the stability of the atom.
because the electric field of the nucleolus is radially symmetrical. And if you really want to get picky, the electron doesn't move in a circle but occupies a spherical probability continuum with indeterminable position and velocity.
an electron. :) and protons are positively charged and chill out in the Nucleus. The Nucleus also includes Neutrons which are, go figure, Neutral charge. So the negatively charged electrons orbit the Nucleus and inside the nucleus are Protons - positive - and Neutrons - neutral. In fact, what keeps the electrons orbiting is the fact that opposite charges are attracted to one another, so the negatively charged electrons are attracted to the positively charged Nucleus. (the nucleus is positive because it's made up of positive particles - protons - and neutral particles - neutrons - so the overall charge is positive.) :) Hope this helped.
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.
The electron does not fall into the nucleus because of the electromagnetic force. This force between the positively charged nucleus and the negatively charged electron keeps them in orbit around each other, creating a stable structure within an atom.
While it is useful to visualize an Electron orbiting an atomic nucleus like a moon orbiting a planet. It is more realistic to think of the Electron as a standing wave (with a fixed number of wave crests and troughs) surrounding the nucleus. The electromagnetic force holds the Electron and nucleus together. The Electron holds a negative electrical charge and the nucleus a positive electrical charge and the two attract one another. Therefore for each positive charge present in the atomic nucleus (the Protons) there must be a balancing negative charge (the Electrons) present round the atom.
A negatively charged electron is attracted by the positively charged nucleus so the electron revolves around the nucleus so that it can generate enough centrifugal force in order that the attractive force is nullified and the electron can stay in its orbit
An electron has a negative charge. This charge affects its behavior in an atom by causing it to be attracted to the positively charged nucleus. This attraction keeps the electron in orbit around the nucleus, forming the electron cloud that defines the atom's size and shape.
You will recall that electrons orbit the nucleus of an atom (or in quantum mechanical terms, they surround the nucleus as a cloud). Under some circumstances, one of those orbiting electrons can fall into the nucleus, where it will react with a proton and convert it into a neutron. This is an electron capture process.
The force that keeps electrons in orbit around the nucleus is called the repelling force of gravity. If there was no gravity the electrons would never stay in orbit but would be floating around in space.
Electrostatic force between the electron and the positively charged nucleus.
the centripetal force along with the attractive force of the electron on the nucleus are balanced by a phenomnon known as the strong nuclear force which prevents the electron from coliding with the nucleus
electrons are in orbits protons are in nucleus an electron keeps revolving in the orbit because of force of attraction but this electron cannot come into the nucleus where proton and neutron reside.

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.
