Question 6

In certain conditions, hydrogen gas produces the emission spectra shown. What causes the bright lines seen in the spectra?

Accepted Answer

After being excited to higher energy levels, electrons return to lower energy levels. In the process, they release photons of light of the energies seen in the spectra.

Answer

Most wavelengths of light are invisible to the naked eye. The bright lines represent the only visible wavelengths of light. The hydrogen gas has no effect on this light.

Answer

When light hits the hydrogen gas, most wavelengths are absorbed by the gas. Only certain wavelengths of light pass through the gas, causing the spectral lines to appear.

Answer

When photons of certain energies hit electrons, the electrons move to higher energy levels.

Question 7

Which statement is part of Bohr's atomic model?

Accepted Answer

Electrons absorb or emit light when they change energy levels.

Answer

Electrons exist as waves and clouds of probability with specific orbits and shapes.

Answer

Electrons orbit the nucleus in narrow ellipses, like how the planets orbit the Sun.

Answer

Electrons with the highest energy are found with orbits of the smallest radius.

Answer

The electron absorbs energy as it moves to a lower energy level.

Answer

The electron absorbs energy as it moves to a higher energy level.

Question 10

What causes the appearance of lines in an emission spectrum?

Accepted Answer

Light is released as an electron moves to a lower energy state.

Answer

An electron is released as light when it moves to a higher energy state.

Answer

An electron is released as light when it moves to a lower energy state.

Answer
