Question
Use the Bohr model energy expression to calculate the energy (in Joules and eV) required to remove an electron from the ground state of a He⁺ ion
Answer :
Word Count : 158
For a hydrogen-like ion, the Bohr model energy expression is [ E_n=-\frac{13.6Z^2}{n^2}\text{ eV} ] For a He⁺ ion, the atomic number (Z=2), and for the ground state (n=1). Therefore, [ E_1=-13.6(2)^2=-54.4\text{ eV} ] The negative sign indicates that the ___ _________ ____ ______ ______ _________ _____ ___ ______.
