Choose the correct statement regarding atomic structure of hydrogen atom?
It contain one proton
It contain 2 electron
It contain 1 neutron
All of the above.
Hydrogen is the lightest element. Its atomic weight is 1.004 amu. Atomic number of hydrogen is one which implies it contains only one proton and one electron. Further, its atomic weight is also nearly 1.
So, number of neutrons
= Atomic weight – Atomic number
= 1 – 1
= 0
