Chemistry Test 3-2

EC, ON, Q#s, LDS

QuestionAnswer
the 3D path an electron probably takes within an energy level orbital
evidence for energy levels comes from the _____ of the elements line emission spectra
proposed that electrons behave as particles and waves (dual wave-particle theory) De Broglie
the bending of a wave as it passes by the edge of an object diffraction
the overlapping of waves interference
His UNCERTAINTY PRINCIPLE states that it is impossible to determine the position and velocity of an electron or any other small particle at the same time Heisenburg
developed the WAVE EQUATION, which laid the foundation for Quantum Theory Schrodinger
describe the energy state and location of electrons quantum numbers
electrons that are not in the highest occupied energy level are called___ inner shell electrons
the first quantum number is called ____ and indicates ____ principal quantum number; main energy level occupied by the atom
specify the properties of atomic orbitals and the properties of electrons within the atomic orbitals quantum number
the second quantum number is called ___ and indicates ___ angular momentum quantum number; the electron's sublevel and the shape of the orbital the electron is moving in whith its sublevel
s orbital has a ___ shape sphere
p orbital has a ___ shape peanut
third quantum number is called ___ and tells ___ magnetic quantum number; a specific orbital section an electron is in at a given point in time along the x, y, z axis
fourth quantum number is called ___ and indicates ___ spin quantum number; direction of electron's spin
the arrangement of electrons in an atom electron configuration
3 types of electron configuration: 1.) electron configuration notation 2.) orbital notation 3.) noble gas notation
an electron occupies the lowest orbital that can receive it (electrons enter the orbitals closest to the nucleus first) Aufbau Principle
no 2 electrons in the same atom can have the same set of 4 quantum numbers (at most, an atomic orbital may contain 2 electrons with opposite spin) Pauli's Exclusion Principle
the idea that electrons witht he same spin eneter each orbital section before electrons with opposite spin eneter is known as ___ Hund's Rule
pair of electrons with opposite spin in the same orbital electron pair

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.
