The energy level excitation potential of a hydrogen -like atom is shown in Figure a Find the value of Z b If initially the atom is in the ground state ,then (i) determine its excitation potential, and m (ii) determine its ionization potential. c Can it absorbe a photom of 42 eV ? d Can it absorbe a photom of 56 eV ? e Calculate the radius of its first Bohr orbit. f Calculate the kinectic and potential energy of an electron in the first orbit.
For hydrogen atom, radius of first Bohr orbit would be
For hydrogen atom, radius of first Bohr's orbit is a for Li^(2+) the radius of first Bohr's orbit is
When hydrogen atom is in its first excited level, its radius is
The ratio of radius of second orbit of hydrogen to the radius of its first orbit is :
Radius of first bohr's orbit of hydrogen atom is 0.53 A then the radius of 3^(rd) bohr orbit is :-
The radius of first Bohr orbit of hydrogen atom is 0.53Å . Then the radius of first Bohr-orbit of mesnoic atom (negative meson has mass 207 times that of electron but same charge) is:
