Electron Configurations - shorthand

Front

What is the order of filling electron orbitals according to the Aufbau principle?

Back

The order of filling is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.

What is the significance of noble gas configurations in electron configurations?

Back

Noble gas configurations simplify electron configurations by using the nearest noble gas to represent the inner shell electrons, making it easier to write and understand.

Front

What is the electron configuration for the element with atomic number 16?

Back

The abbreviated electron configuration for sulfur (atomic number 16) is [Ne] 3s2 3p4.

Front

What is the electron configuration for silver (Ag)?

Back

The abbreviated electron configuration for silver (atomic number 47) is [Kr] 5s2 4d9.

Front

What is the electron configuration for boron (B)?

Back

The noble gas configuration for boron (atomic number 5) is [He] 2s2 2p1.

Front

What is the electron configuration for beryllium (Be)?

Back

The noble gas configuration for beryllium (atomic number 4) is [He] 2s2.

Front

What is the maximum number of electrons that can occupy the 3d subshell?

Back

The maximum number of electrons that can occupy the 3d subshell is 10.

Front

What is the difference between the ground state and excited state electron configurations?

Back

The ground state configuration has electrons in the lowest energy levels, while the excited state configuration has one or more electrons in higher energy levels.

Front

How do you determine the electron configuration for transition metals?

Back

For transition metals, the 4s subshell is filled before the 3d subshell, and the electron configuration may involve partially filled d orbitals.

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.
