Represent an electron ‘e’ in term of its symbol showing the subscript and superscript value.
Is it possible for the atom of an element to have one electron, one proton and no neutron. If so, name the element.
Assertion: Proton can be defined as a hydrogen ion (H+).
Reason: These photons are produced when one electron is removed from one hydrogen atom.
