Electron Configurations2 & Orbital Notation

Front

What is the electron configuration for Vanadium (V)?

Back

[Ar] 4s2 3d3

Front

How do you draw a Lewis dot diagram for Magnesium (Mg)?

Back

The Lewis dot diagram for Magnesium shows two dots around the symbol 'Mg', representing its two valence electrons.

Front

How many electrons can the d sublevel hold?

Back

The d sublevel can hold a maximum of 10 electrons.

Front

What is Hund's Rule?

Back

Hund's Rule states that electrons will fill degenerate orbitals singly before pairing up.

Front

Which orbital shows a violation of Hund's Rule?

Back

The D orbital can show a violation of Hund's Rule if it has paired electrons before all degenerate orbitals are singly occupied.

Front

What atom matches the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁸?

Back

The atom is Nickel (Ni).

Front

What is the maximum number of electrons in the s sublevel?

Back

The s sublevel can hold a maximum of 2 electrons.

Front

What is the shape of the p orbital?

Back

The p orbital has a dumbbell shape.

Front

What is the principal quantum number (n)?

Back

The principal quantum number (n) indicates the energy level of an electron in an atom.

Front

What is the difference between the 3d and 4s orbitals in terms of energy?

Back

The 4s orbital is lower in energy than the 3d orbital when filling electrons, but 3d is filled after 4s.
