Do electrons reside inside the nucleus? Explain.
Electrons are always partially in the nucleus. In electron capture, an atomic electron is absorbed by a proton in the nucleus, turning the proton into a neutron. The electron starts as a regular atomic electron, with its wavefunction spreading through the atom and overlapping with the nucleus.
Electrons in the atom do enter the nucleus. In fact, electrons in the s states tend to peak at the nucleus. Electrons __________ ___ ____ _______ ____ ________ ____.
