Relativistic quantum chemistry

Relativistic quantum chemistry is a type of chemistry where scientists use special equations to understand how different types of atoms are affected by the energy of being close to other atoms that are moving very quickly. It's important for scientists to understand how atoms interact because it helps them to understand how molecules work and how they can use them to make things. To understand how atoms interact, scientists need to use special kinds of equations that take into account how they are affected by the energy of moving really quickly. This kind of chemistry is called relativistic quantum chemistry.
