Question

The emission spectrum of hydrogen shows discrete, bright, colored lines. Which characteristic of the Bohr model is best supported by this observation?
a.Energy is released when an electron moves to a higher energy level.

b.Smaller atoms have fewer spectral lines than larger atoms.

c.The energy of an electron increases with distance from the nucleus.

d.Electrons cannot exist in locations other than in specific orbits.

Answer 1

D.Electrons cannot exist in location other than specific orbits.

Answer 2

Answer is: d.Electrons cannot exist in locations other than in specific orbits.

According to the Bohr model of the atom:

1. Energy levels of electrons are discrete (certain discrete values of energy)., that is why hydrogen shows discrete, bright, colored lines.

2. Electrons orbit the nucleus in orbits that have a set size and energy.

3. Electrons can jump from one energy level to another, absorbing or emitting electromagnetic radiation with a frequency ν (energy difference of the levels).
