my theory is that electrons slow down when cooled... so since they have less force pulling them out do they get sucked it..??

Hi. No, but they can, and do, get pushed in by gravity in a neutron star. Each electron hits a proton, their charges cancel and there you go.

Think of an electron as a standing wave on a violin sting. They do not actually orbit the nucleus so cannot get 'sucked in'. More interestingly if you could cool something down to absolute zero you would couple the temperature of the nucleus to that of the macroscopic world, it's about 4000K. Zero point energy.
I know you can't really talk about the temperature of a nucleus.

At the lowest possible theoretical temperature(-273.15 degrees Celsius), all molecular motion stops. (This is 'practically' impossible!) The electron will crash into the nucleus as it is no longer in motion. However, when it cashes, the impact will generate some energy(heat), and the heat will disperse throughout the surroundings, so -273.15 degrees Celsius can never be attained in a laboratory. In THEORY, the electron would collide with the nucleus.

1) There is not force "pulling them out" centrifugal forces do not exist.
2) Electrons do not orbit the nucleus in the way you seem to think. They do not have elliptical orbits.
3) Electrons cannot fall below certain energy states without being bombarded with special particles in nuclear chemistry.

It is not the movement of the electrons that keep them from falling into the nucleus. The electrons are restricted to quantum states (energy levels) and cannot naturally fall below the lowest level.

No, but if group of atoms cool down to extreme they begin to behave as though if they're twins. Google condensate, superfluid, conensate physics... etc.

The nucleus is positively charged and would repel the negatively charged electrons, even at absolute zero. (think particles floating in space)
