➤Electrons in the atom do enter the nucleus. In fact, electrons in the 's' states tend to peak at the nucleus. Electrons are not little balls that can fall into the nucleus under electrostatic attraction.

➤Rather, electrons are quantized wavefunctions that spread out in space and can sometimes act like particles in limited ways.

➤An electron in an atom spreads out according to its energy. The states with more energy are more spread out. All electron states overlap with the nucleus, so the concept of an electron "falling into" or "entering" the nucleus does not really make sense. Electrons are always partially in the nucleus.
