Honors 2 Electron Configuration Test

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, represented by a series of numbers and letters indicating the energy levels and types of orbitals occupied by electrons.

What is the electron configuration for Arsenic (As)?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p³.

Front

What is the electron configuration for As^-2?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p¹.

Front

What is the maximum number of electrons in the p sublevel?

Back

6 electrons.

Front

What noble gas is used for shorthand configuration of Tellurium (Te)?

Back

Krypton (Kr).

Front

What is orbital notation?

Back

A representation of the electron configuration of an atom using arrows to indicate the spin of electrons in orbitals.

Front

How many orbitals are in the d sublevel?

Back

5 orbitals.

Front

What is the Pauli Exclusion Principle?

Back

No two electrons in an atom can have the same set of four quantum numbers, meaning each orbital can hold a maximum of two electrons with opposite spins.

Front

What is Hund's Rule?

Back

Electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up.

Front

What is the Aufbau Principle?

Back

Electrons occupy the lowest energy orbitals first before filling higher energy orbitals.
