Chem Chap 4 Sec 3

Electron Configurations

QuestionAnswer
The arrangement of electrons in an atom is known as the atom’s electron configuration
The lowest energy arrangement of the electrons for each element is called the element’s ground-state electron configuration
What principle states that an electron occupies the lowest-energy orbital that can receive it Aufbau principle
no two electrons in the same atom can have the same set of four quantum numbers is what principle Pauli exclusion principle
The Pauli Exclusion principal,angular momentum, and magnetic quantum numbers specify what the energy, shape, and orientation of an orbital
Whose rule says orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron, and all electrons in singly occupied orbitals must have the same spin state. Hund’s rule
In orbital notation, an unoccupied orbital is represented by a line, , with the orbital’s name written underneath the line
An orbital containing one electron is represented as
An orbital containing two electrons is represented as ↑↓
The lines are labeled with the principal quantum number and sublevel letter.
How is the Electron-configuration notation different form orbital notation eliminates the lines and arrows of orbital notation. Instead, the number of electrons in a sublevel is shown by adding a superscript to the sublevel designation
What does the superscript indicate The superscript indicates that one electron is present
The highest-occupied energy level is the electron-containing main energy level with the highest principal quantum number
electrons that are not in the highest-occupied energy level. inner-shell electrons
The Group 18 elements are called the noble gases.
Name the Group 18 elements helium, neon, argon, krypton, xenon, and radon
an outer main energy level occupied, in most cases, by eight electrons noble-gas configuration
The arrangement of electrons in an atom is Electron configuration
The lowest-energy arrangement of the electrons for each element Ground-state electron configuration
The electron containing main energy level with the highest principle quantum number Highest occupied energy level

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.
