Electrons in Atoms

QuestionAnswer
Energy that behaves like a wave as it moves through space electromagnetic radiation
distance between two similar points on a wave (lambda) wavelength
the SI unit is the hertz (Hz), where 1 Hz = 1 wave/second = 1/s; how many waves pass a certain point each second (v, nu) frequency
height of wave from origin to crest (psi) amplitude
What is the order for EM Spectrum? Radio, microwave, infrared, visible, ultraviolet, x-ray, gamma ray
discovered that minimum amount of energy that can be gained or lost by an atom Max Planck
when metals are hit with specific frequency of light, they emit electrons photoelectric effect
discovered that you can combine wave and particle theory of light Albert Einstein
specific frequency of light are given off by different elements emission spectrum
Discovered quantum model for the hydrogen atom, treated the electron as a particle in circular orbits Niels Bohr
energy levels of the electron, ground state, and each has a quantum number, "n" orbits
electron "jumps" to a higher energy orbit "Excited state"
What are the flaws of Bohr's model? only works for hydrogen, doesn't explain chemical properties, and energy levels aren't circles

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.
