Electron configuration and trends

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 is the noble gas configuration for an element?

Back

A shorthand notation for electron configuration that uses the nearest noble gas to represent core electrons, simplifying the representation of valence electrons.

Front

Which element has the electron configuration [Ne] 3s² 3p³?

Back

Phosphorus (P)

What is the electron configuration for Argon (Ar)?

Back

1s² 2s² 2p⁶ 3s² 3p⁶

Front

What is the chemical family of elements in Group 1 of the periodic table?

Back

Alkali Metals.

Front

What is the electron configuration for Krypton (Kr)?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶

Front

Which block of the periodic table does Argon (Ar) belong to?

Back

p block.

Front

What is the significance of the periodic table's groups?

Back

Elements in the same group have similar chemical properties and the same number of valence electrons.

Front

What is the electron configuration for Potassium (K)?

Back

[Ar] 4s¹

Front

What is the difference between s, p, d, and f orbitals?

Back

s orbitals are spherical, p orbitals are dumbbell-shaped, d orbitals have more complex shapes, and f orbitals are even more complex.
