Atomic Structure Question 377

Question: The energy of an electron in first Bohr orbit of Pi- atom is 13.6eV . The energy value of electron in the excited state of Li2+ is:

Options:

A) 27.2eV

B) 30.6eV

C) 30.6eV

D) 27.2eV

Show Answer

Answer:

Correct Answer: C

Solution:

  • For Li2+ ion E=13.6×Z2n2=13.6×(3)2(2)2

=13.6×94=30.6eV
