Question 95

An electron in an atom is in allowed orbit A. The atom then absorbs electromagnetic radiation twice in succession. Each time, 3.0 × 10-19 J of energy is transferred to the electron. The table shows the energy of each allowed orbit relative to orbit A.

OrbitEnergy relative to orbit A (J)
A0
B3.0 × 10-19
C6.0 × 10-19
D8.0 × 10-19

Which orbit does the electron occupy after both absorptions? Explain your answer.
