Answers
Answer:
(i)The expression for the energy associated with nth orbit in hydrogen atom is E
(i)The expression for the energy associated with nth orbit in hydrogen atom is E n = n 2−2.17×10 −18J/atom.
(i)The expression for the energy associated with nth orbit in hydrogen atom is E n = n 2−2.17×10 −18J/atom.The energy associated with fifth orbit is E
(i)The expression for the energy associated with nth orbit in hydrogen atom is E n = n 2−2.17×10 −18J/atom.The energy associated with fifth orbit is E n = 5 2−2.17×10 −18 J/atom
=−8.68×10 −20 J.
J. (ii) The radius of Bohr's nth orbit is given by the expression r
J. (ii) The radius of Bohr's nth orbit is given by the expression r n =0.0529n 2 nm.
J. (ii) The radius of Bohr's nth orbit is given by the expression r n =0.0529n 2 nm.For fifth orbit, the radius is r
J. (ii) The radius of Bohr's nth orbit is given by the expression r n =0.0529n 2 nm.For fifth orbit, the radius is r 5
J. (ii) The radius of Bohr's nth orbit is given by the expression r n =0.0529n 2 nm.For fifth orbit, the radius is r 5
J. (ii) The radius of Bohr's nth orbit is given by the expression r n =0.0529n 2 nm.For fifth orbit, the radius is r 5 =0.0529×5 2nm
=1.3225 nm.
