what do you think you know about physics, physics is the study of matter under the effect of energy, but does this includes solid states bodies, atoms at ground states, object at microscopic size or object moving faster than light? these and more is what prompt me to ask again what is physics?
what does the following element description actually mean 238 u 92
it means the nuclide is an isotope of uranium,
with 238-92 = 146 neutrons, all isotopes of an atom behave same way chemically,
but only the nuclear proper, mass and density that varies.
