Question

Part A The bright lines of an emission spectrum are the result of View Available Hintis) electrons losing energy as they spiral into the nucleus of an atom electrons transitioning from a higher energy level to a lower energy level electrons being ejected from atoms electrons transitioning from a lower energy level to a higher energy level Submit Provide Feedback

Answer 1

Answer:

1. Bright Lines in the emission spectrum were due to transitions in which an electron moved from a higher-energy orbit with a larger radius to a lower-energy orbit with smaller radius.i.e, answer is option 2^nd.
2. Heisenberg's uncertainity principle tells us that the more accurately we know the position of a particle ,the less accurately we can know the velocity of that particle. i.e, answer is option 1^st.

Please do give a thumbs up.
