Asemmisa {{asɛmmisaAhyɛnsode}}
12.

This electron (from question 16) moves from a ________ energy state to a ________ energy state.

Asemmisa {{asɛmmisaAhyɛnsode}}
13.

Match each image with the correct electron transition.

  • n = 6 to n = 2

  • n = 5 to n = 2

  • n = 4 to n = 2

  • n = 3 to n = 2

  • n = 2 to n = 6

  • n = 2 to n = 4

  • n = 2 to n = 3
