Final Review Flashcard 3

Front

What does an orbital diagram represent?

Back

An orbital diagram visually represents the arrangement of electrons in an atom's orbitals, showing the distribution of electrons among the various energy levels and sublevels.

Front

What is the Pauli Exclusion Principle?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers, meaning that an orbital can hold a maximum of two electrons with opposite spins.

Front

What is Hund's Rule?

Back

Hund's Rule states that electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up, to minimize electron-electron repulsion.

Front

What is the electron configuration for Oxygen (O)?

Back

The electron configuration for Oxygen is 1s² 2s² 2p⁴.

Front

How many valence electrons does Chlorine (Cl) have?

Back

Chlorine has 7 valence electrons.

Front

What is the significance of the 2p orbital?

Back

The 2p orbital is one of the sublevels in the second energy level, capable of holding a maximum of 6 electrons, and is important for understanding chemical bonding and reactivity.

Front

What is the maximum number of electrons that can occupy the 3rd energy level?

Back

The maximum number of electrons that can occupy the 3rd energy level is 18.

Front

What is the difference between an atom's ground state and excited state?

Back

An atom's ground state is its lowest energy configuration, while an excited state occurs when one or more electrons have absorbed energy and moved to a higher energy level.

Front

What element is represented by the orbital diagram with 6 electrons in the 2p sublevel?

Back

The element represented is Carbon (C).

Front

What is the electron configuration for Neon (Ne)?

Back

The electron configuration for Neon is 1s² 2s² 2p⁶.
