(a) Hydrogen atom (b) Singly ionised helium atom (He+)
(c) Deuteron atom (d) Singly ionised neon atom (Ne+)

| Hydrogen Atom |
Solution:
Before solving this question we must have to
know that the Bohr’s Atomic model is valid ‘only’ for ‘ Single Electron Species’.
i.e. it is valid only for atoms or ions which has only one electron revolving
around its nucleus.
Option a:
Hydrogen atom
A hydrogen atom consists of one proton in
nucleus and only one electron revolving around it. As this is a Single Electron
Species’, ‘yes’ Bohr’s atomic Model is applicable for Hydrogen atom.
Option b:
Singly ionised helium atom (He+)
A Singly ionised helium atom (He+)
consists of two protons and two neutrons in nucleus and only one electron
revolving around it. As this is a Single Electron Species’, ‘yes’ Bohr’s atomic
Model is applicable for Singly ionised helium atom (He+)
Option c:
Deuteron atom
A Deuteron atom which is isomer of hydrogen atom consists of
a proton and a neutron in nucleus and only one electron revolving around it. As
this is a Single Electron Species’, ‘yes’ Bohr’s atomic Model is applicable for
Deuteron atom
Option d:
Singly ionised neon atom (Ne+)
A Singly ionised neon atom (Ne+)
consists of ten protons and ten neutrons in nucleus and nine
electrons revolving around it. As this is
NOT a Single
Electron Species’, ‘NO’ Bohr’s atomic Model is NOT applicable
for Deuteron atom
Therefore the
correct answer is option ‘d’
