Question

As per Bohr model, the minimum energy (in eV) required to remove an electron from the ground state of doubly ionized Li atom (Z= 3) is (A) 1.51 (B) 13.6 (C) 40.8 (D) 122.4

Tardigrade Admin · Accepted Answer

For hydrogen and hydrogen like atoms En=-13.6((Z2)/(n2))eV Therefore, ground state energy of doubly ionized lithium atom (Z = 3, n = 1) will be E1(-13.6)((3)2/(1)2)=-122.4eV ∴ Ionization energy of an electron in ground state of doubly ionized lithium atom will be 122.4 eV.

Q. As per Bohr model, the minimum energy (in eV) required to remove an electron from the ground state of doubly ionized Li atom (Z= 3) is

1.51

13.6

40.8

122.4

For hydrogen and hydrogen like atoms En​=−13.6(n2)(Z2)​eV Therefore, ground state energy of doubly ionized lithium atom (Z = 3, n = 1) will be E1​(−13.6)(1)2(3)2​=−122.4eV ∴ Ionization energy of an electron in ground state of doubly ionized lithium atom will be 122.4 eV.
