Protons and electrons stick to each other as much as they can, but kinetic energy and quantum mechanics keep them from holding still.
Protons and electrons are attracted to each other because the positive electric charge of the proton is attracted to the negative charge of the electron. But, if they two particles find each other so attractive, why don’t protons and electrons stick together? Orbits and Waves In a sense, protons and […]

Thermal polish is sometimes sold as mood polish. (LelĂȘ Breveglieri)
Thermal nail polish is a type of polish that changes colors according to temperature. It’s like wearing a mood ring on your nails, except most thermochromic polish only switches between two colors rather than displaying the whole rainbow. The cool (or hot!) effect involves a bit of chemistry. Here’s how […]

An electron is a unit of matter with a negative electrical charge. (Anne Helmenstine)
Atoms are made of protons, neutrons, and electrons. Of these three particles, the electron has the smallest mass. Here is the definition of the electron, along with its word origin, history, and interesting facts. Electron Definition An electron is a stable subatomic particle with a negative electrical charge. Each electron […]
