The electrons are negatively charged and the nuclei are positively charged. Why didn't the electrons fall into the nuclei?

Posted on August 25, 2022Categories Regulated diode   Leave a comment on The electrons are negatively charged and the nuclei are positively charged. Why didn't the electrons fall into the nuclei?

It's not that the electrons don't fall to the nucleus, but typically they don't fall to the nucleus, otherwise the atom is too unstable. But under the right conditions, electrons can fall to the nucleus, but it takes a lot of energy. Here's a layman's explanation of why this is so. First of all, say the scientists study atomic model, which the rutherford model "planet" a representative, he through the alpha particle scattering experiment demonstrated that most of the atomic … Continue reading "The electrons are negatively charged and the nuclei are positively charged.
