it is the branch of physics that deals with the structure and the behaviour of an atom is called atomic physics
The answer is Atomic Physics. Atomic physics is the study of atomic interractions.
In physics this is called mechanics.Quantum mechanics is the branch of physics that deals with the motion of particles by their wave properties at the atomic and subatomic levels.
Physics is the science of motion and does not have anything to do with economics.
It means, physics of the nucleus - meaning the atomic nucleus.
Physics. More specifically sub-atomic physics
thermodynamics,mechanics,optics,electricity,atomic physics etc.
I suppose that physics is more important.
Nuclear Physics
That is by definition.
Atomicity is having atoms. Also the number of atoms in a molecule.
All physics deals with energy and matter. In effect that is almost a complete definition of what Physics IS.
Physics is the general term used for the discipline that studies and models the types of energy and energy sources. But there are specific labels for specific kinds of energy studies. These in include, but are not limited to, nuclear physics, sub-atomic physics, thermodynamics, fluid dynamics, mechanics, astrophysics, physical chemistry, and so on. The definition of physics is "...the branch of science concerned with the nature and properties of matter and energy. " [Dictionary]
