Electron Configuration

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 are the main energy levels in an atom?

Back

The main energy levels are labeled as n=1, n=2, n=3, etc., where n represents the principal quantum number.

Front

What is the maximum number of electrons in a given energy level?

Back

The maximum number of electrons in an energy level is given by the formula 2n², where n is the principal quantum number.

Front

What is a p block element?

Back

Elements found in groups 13 to 18 of the periodic table, characterized by having their outermost electrons in p orbitals.

Front

What is the electron configuration for Neon (Ne)?

Back

1s² 2s² 2p⁶.

Front

How do you determine the number of valence electrons in an atom?

Back

The number of valence electrons is determined by the outermost energy level of the atom.

Front

What is the Pauli Exclusion Principle?

Back

No two electrons in the same orbital can have the same spin.

Front

What is Hund's Rule?

Back

Every orbital in a sublevel is singly occupied before any orbital is doubly occupied, and all singly occupied orbitals have the same spin.

What is the electron configuration for Aluminum (Al)?

Back

1s² 2s² 2p⁶ 3s² 3p¹.

Front

What is the significance of the Aufbau Principle?

Back

Electrons occupy the lowest energy orbitals first before moving to higher energy orbitals.
