The Li2+ ion is very similar to the hydrogen atom, in that it has one electron and energy levels similar to the hydrogen atom. However, the relation = − (

rather the relation = −2+ (

2) where the constant 2+=1.96x10-17J.
Use this relation to determine the third ionization energy, which is energy required to remove the last
electron from a Li2+ ion in kJ/mol, if the ion starts off in the ground state (Li2+ → Li3+
+ e-
).

In saturated organic compounds, all the bonds between carbon atoms are called?

Which statement best describes the flow of energy in this scenario
