Bohr Model

This stack prepares me for the Bohr model quiz in Chemistry

QuestionAnswer
What is the Bohr Model? The Bohr model describes how the atoms were believes to have specific orbits around the nucleus.
What is the Emission Spectra? The Emission Spectra is the a spectrum of the electromagnetic radiation emitted by a substance.
Explain why elements produce their own colors characteristic colors when the emit photons. They can release energy only equal to difference of the energy level their electrons can jump so, as arrangement of electrons is different in different elements so is the difference in frequencies they emit, hence the different colors.
Why are the bright - line emission spectra of elements unique? Each element produces a unique bright line spectra because no two elements have the same number of electrons hence when the electron moves from a higher level to a lower level, it produces a unique light frequency.
How does the Bohr model explain the bright line spectra of hydrogen? Since not two elements have the same number of electrons, as an energized electron moves from a higher level to a lower level, it produces a photon (visible light).
How do the energy transitions of the hydrogen atom explain why some emission spectra are located in the ultraviolet, visible, or infrared? If an electron only moves a little bit (from a high energy level to a lower energy level) it will produce ultraviolet light. A "Medium" ammount = visible. "A Lot" = infrared.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
