Electron configuration and Orbital Notation

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What does the notation 1s² represent?

Back

It indicates that there are 2 electrons in the 1s orbital.

Front

How many total electrons can the p sublevel hold?

Back

The p sublevel can hold a maximum of 6 electrons.

Front

What is the maximum number of electrons that can occupy the d sublevel?

Back

The d sublevel can hold a maximum of 10 electrons.

Front

What is noble-gas notation?

Back

A shorthand method of writing electron configurations using the electron configuration of the nearest noble gas.

Front

What is the electron configuration of neon?

Back

1s² 2s² 2p⁶.

Front

How many electrons does calcium have based on its noble-gas notation [Ar]4s²?

Back

Front

What is the correct noble-gas notation for chlorine?

Back

[Ne]3s² 3p⁵.

Front

What is the significance of the Aufbau principle in electron configuration?

Back

It states that electrons fill orbitals starting from the lowest energy level to the highest.

Front

What does Hund's rule state?

Back

Electrons will occupy degenerate orbitals singly before pairing up.
