Question

the ionization enthalpy of hydrogen atom is 1.3312(10)^6 joule per mol the energy required to extract the electron in the atom from n equal to 1 and equal to 2 is

Answer 1

2=−1.32×106×(1)222  

=−3.28×105Jmol−1

E1=−1.312×106Jmol−1

ΔE=E2−E1

=−3.28×105−(−13.2×106)

=9.84×105Jmol−1

Answer :9.84×105Jmol−1
