Chem BM 2

QuestionAnswer
Wavespeed equation speed = length x frequency
What was the double slit experiment 2 slits made in an object,, 2 wave propogations created when electrons shot through, showed interference pattern
what did the double slit experiment prove light and electrons act as waves
what is the photolelectric effect electrons emitted from any surface when light of a high enough frequency shines on that surface
what did the photoelectric effect prove light acts as a wave and a particle
define line emission spectrum light shines through a prism produces a series of different frequencies that make up that light
what happenes when light hits an atom electrons get absorb energy and go up a level, then releases E as certain wavelengths of light and goes back
difference between photoelectric effect and excited state pe = electron gets so excited it flies away excited = electron just goes up an orbital
define principal quantam number. what is it equal to? the main energy that the electron is in.
formula for number of electrons per E level 2n^2
define angular quantam number is the shape of the orbital (like p or s)
define magnetic quantam number orientation of the orbital
define spin quantam number tells whether electron spin is clockwise or counterclockwise
Define heisenberg uncertainty principle impossible to determine the position and velocity of an electron at the same time
define aufbau principal an electron occupies lowest E level it can and fills from the bottom up
define hunds rule if there are 2 or more empty orbitals of the same E level, each orbital takes one electron before subshell orbitals fill with second electron
what is electronegativity E it takes to add an electron to atom
what is electron affinity E released when neutral atom gets an electron
define pauli exclusion principle each orbital can hold max of 3 electrons with opposite spin

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.
