Explanation:
So scientist around the world can share there info without having to convert and doing extra work.
Two different atoms have nine protons each and the same mass. However, one is neutral while the other has a negative charge then the atomic structure of the both atom are of same element but one of them is electrically neutral and other has a stable electronic configuration
An atom is said to be neutral because it has an equal number of electron and proton in it and if two different atom have nine proton each and same the mass but one is neutral while the other has a negative charge and the mass of an atom is determined by the number of proton and neutron is present in its nucleus and since both the given atom have 9 proton and the same mass and they must also have the same number of neutron
This implies both the atom have the same nucleus but different charges so it can be concluded that they both the atom of the same element but one of them is electrically neutral and other has stable electronic configuration
