Question

During a chemical reaction, the number of electrons changes but number of protons remain constant why?

Answer 1

Answer:

In a chemical reaction the total mass before the reaction and after the reaction is constant this includes protons, neutrons, electrons!! The arrangement of the atoms changes, the orbital structure changes, the location of the electrons in orbitals changes but the number of electrons DOESN'T change!

Answer 2

Hello Friend!

↪ Atomic number of an element is nothing but number of protons.

↪ During a chemical reaction, the number of electrons only changes, but the number of protons does not change. So, the atomic number does not change.
