Respuesta :
If an atom loses a proton then Its mass stays the same, and it is still the same element.
What is proton?
A proton would be a stable elementary particle having the symbols p, [tex]H^{+}[/tex], or 1 [tex]H^{+}[/tex], and an elementary electric charge of +1e. It has a mass that would be slightly lower than those of a neutron as well as being 1836 times heavier than an electron according to the proton-to-electron mass ratio.
What is atom ?
The smallest component of ordinary stuff that makes up a chemical element would be an atom. Atoms that are neutral or ionized make up every solid, liquid, gas, as well as a form of plasma. Atoms are generally incredibly tiny, measuring up to 100 picometers around.
Therefore, If an atom loses a proton then Its mass stays the same, and it is still the same element.
