Test - Electron Configuration (2024-2025)

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating how many electrons occupy each energy level and sublevel.

Front

How many electrons can the first energy level hold?

Back

2 electrons.

Front

What is the maximum number of electrons in the second energy level?

Back

8 electrons.

Front

What is the noble gas configuration for Neon?

Back

[He] 2s² 2p⁶.

Front

What does the principal quantum number indicate?

Back

The main energy level of an electron in an atom.

Front

What is an orbital diagram?

Back

A visual representation of the arrangement of electrons in an atom, using arrows to represent electrons in orbitals.

Front

How many orbitals are in the p sublevel?

Back

3 orbitals.

Front

What is the electron configuration for Oxygen (O)?

Back

1s² 2s² 2p⁴.

Front

What is the significance of the Aufbau principle?

Back

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

Front

What is Hund's rule?

Back

Electrons will occupy degenerate orbitals singly before pairing up.
