$(e)$ How many neutrons are present in a hydrogen atom?
(N/A) The neutron was discovered by James Chadwick.
$(b)$ According to Thomson's model of an atom,the negative and positive charges are equal in magnitude,which makes the atom electrically neutral as a whole.
$(c)$ The maximum number of electrons that can be accommodated in the outermost shell is $8$.
$(d)$ Atoms of different elements having the same atomic mass but different atomic numbers are called isobars.
$(e)$ $A$ hydrogen atom contains $0$ neutrons.
