Electron Configuration, Bohr Model, Orbital Diagram

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

What is the Bohr model of the atom?

Back

A model that depicts electrons orbiting the nucleus in fixed paths or energy levels, with quantized energy states.

Front

What does an orbital diagram represent?

Back

A visual representation of the arrangement of electrons in an atom's orbitals, showing the distribution of electrons among the various orbitals.

Front

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

Back

2 electrons.

Front

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

Back

8 electrons.

Front

What is the significance of the Pauli Exclusion Principle?

Back

No two electrons in an atom can have the same set of four quantum numbers, meaning each orbital can hold a maximum of two electrons with opposite spins.

Front

What is the Aufbau principle?

Back

Electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is the meaning of 'ground state' in terms of electron configuration?

Back

The lowest energy state of an atom, where electrons are in the closest possible orbitals to the nucleus.

Front

What happens when an electron absorbs energy?

Back

It can move to a higher energy level or orbital, becoming excited.

Front

What is the relationship between frequency and color of light?

Back

The frequency of a photon determines the color of light; higher frequency corresponds to colors like violet, while lower frequency corresponds to red.
