Answer 1

Answer #1

From Bohr's model.

the energy of an electron in nth orbit in an unielectron species = -2.18x10^-18 Z² /n² J/atom

energy of first orbit is the lowest possible energy for any atom.

a) E1 of Li+2 = -2.18x10^-18 Jx 3² /1

=-2.42 x10^-19 J/atom

b)Thus E1 of He+ = -2.18x10^-18 x 2² /1

= - 5.45 x10^-19 J /atom

c) energy of n=6 for H atom = -2.18x10^-18 / 6² J /atom

=-6.055x10^-20 J

d) energy of 8th orbit in H- atom

= -2.18x10^-18 / 8² J /atom

= -3.406x10^-20 J
