50 points! answer fast! an electron is present at an energy level with an energy of 16.32 x 10−19 j. during a transition to another level, 5.4 x 10−19 j of energy was released. which of the following is true about the present state of the electron? the electron moved down to an energy level and has an energy of 10.92 x 10−19 j. the electron moved down to an energy level and has an energy of 21.72 x 10−19 j. the electron moved up to an energy level and has an energy of 10.92 x 10−19 j. the electron moved up to an energy level and has an energy of 21.72 x 10−19 j.

Given:

The initial energy of the electron Einitial = 16.32 * 10⁻¹⁹ J

The energy released i.e the change in energy ΔE = 5.4 * 10⁻¹⁹ J

To determine:

The final energy state Efinal of the electron

Explanation:

Since energy is being released, this suggests that Efinal < Einitial

i.e. ΔE = Einitial - Efinal

Efinal = Einitial - ΔE = (16.32 - 5.4)*10⁻¹⁹ = 10.92 * 10⁻¹⁹ J

Ans: A)

The electron moved down to an energy level and has an energy of 10.92 * 10⁻¹⁹ J

Hello there! The calculations above are correct, however, the answer is: C.  The electron moved up to an energy level and has an energy of 10.92*10^-19 J
