Helium atom can be excited to 1s 2p configuration by light of 58 44 nm The lowest excited state with configuration 1s 2s lies 4857 cm1 1 A below the 1s 2p state What would be the average He H bond energy so that HeH2 could form non endothermically from the lowest excited singlet state of helium Neglect any difference between AG and AH and take AH as 218 kJ mol 1 1614 kJ mol 1 2 1212 kJ mol 1 3 912 kJ mol 1 4 1511 kJ mol 1
