Solution

Hydrogen:
Hydrogen is the element having only 1 electron,1 proton, and no neutron.
Hydrogen has atomic number 1, which means it has only one proton as the atomic number is equal to the number of protons.
Also, it has mass number 1 which is the sum of nucleons. that implies Hydrogen has no neutron.
So, It is possible to have 1 electron, 1 proton, and no neutron for an element. e.g. Hydrogen.
