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?
which of the following properties of an element is least likely to change with beta decay?
the atomic mass, the atomic mass always remain unchanged in allthe two types of beta decay, beta plus decay
reduce the atomic number while beta minus decay increase the atomic number but
the mass never change
