Using the Bohr model, determine the lowest possible energy, in joules, for the electron in the Li2+ ion.

E = - 19.611× J

Explanation: The lowest possible energy can be calculated using the formula:

where:

Z is atomic number of the atom;

k is a constant which contains other constants and is 2.179× J

n is a layer;

For the lowest possible, n=1.

Atom of Lithium has atomic number of Z=3

Substituing:

J

The energy for the electron in the ion is - 19.611 joules
