WebbWe have to find the ratios of energies of the 2nd orbit of H, He +, Li 2 + Also, the number of orbits (n) = 2. Apply energy formula for single-electron species: We know that energy of hydrogen-like species = -13. 6 z 2 n 2 eV. Now, As n= 2 (n = number of orbits) for all species given and -13.6 is also constant for H, He +, Li 2 + So, E α Z 2 ... dauphin island town crierWebbThe maximum and minimum speeds of a comet that orbits the Sun are 80 and 10 km/s respectively.
