Electron Configuration and Vocabulary

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, described by a series of numbers and letters (e.g., 1s² 2s² 2p⁶).

Front

What is the maximum number of electrons in the 3rd principal energy level?

Back

18 electrons.

Front

How many orbitals are in the p sublevel?

Back

3 orbitals.

Front

What is a valence electron?

Back

An electron in the outermost shell of an atom that can participate in chemical bonding.

Front

What is the noble gas shorthand notation for electron configuration?

Back

A method of writing electron configurations using the nearest noble gas to simplify the notation.

Front

What is an orbital diagram?

Back

A visual representation of the electron configuration of an atom, showing the distribution of electrons in orbitals using arrows.

Front

What element has the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s²?

Back

Krypton (Kr).

Front

What is the principal energy level?

Back

The main energy level of an electron in an atom, denoted by a number (n=1, 2, 3, etc.).

Front

How many electrons can the d sublevel hold?

Back

10 electrons.

Front

What is the difference between electron configuration and orbital diagram?

Back

Electron configuration is a notation that shows the distribution of electrons, while an orbital diagram visually represents the arrangement of electrons in orbitals.
