Chapter 3.2 – 3.3 (Openstax.org – Atoms First)HomeworkModel 1.Bohr ModelEn= -2.18 x 10-18J (1/n2)(n = 1,2, 3, . . .)∆ E=−2.18x1018J(1nf21ni2)1.Calculate the energy of an electron in n=5 level in a hydrogen atom?
2.Calculate the change in energy,∆ E,when an electron in a hydrogen atom makes a transitionfrom an orbital in which n = 5 to an orbital in which n = 2.
3.Calculate the change in energy,∆ E,when an electron in a hydrogen atom makes a transitionfrom an orbital in which n = 2 to an orbital in which n = 5.
