AKS 3g: Bohr Model and electron configurations

Front

What is the Bohr Model?

Back

The Bohr Model is a theory that describes the structure of an atom, proposing that electrons orbit the nucleus in fixed paths or energy levels.

Front

How many electrons can the first energy level hold?

Back

The first energy level can hold a maximum of 2 electrons.

Front

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

Back

The second energy level can hold a maximum of 8 electrons.

Front

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

Back

The third energy level can hold a maximum of 18 electrons, but for many elements, it is often considered to hold 8 for simplicity.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost energy level of an atom that are involved in chemical bonding.

Front

How many valence electrons does Sodium (Na) have?

Back

Sodium (Na) has 1 valence electron.

Front

What is the electron configuration for Neon (Ne)?

Back

The electron configuration for Neon (Ne) is 1s² 2s² 2p⁶.

Front

What is the significance of the electron configuration?

Back

Electron configuration determines how an atom interacts with other atoms and its chemical properties.

Front

What is the electron configuration for Carbon (C)?

Back

The electron configuration for Carbon (C) is 1s² 2s² 2p².

Front

How do you determine the number of valence electrons from the periodic table?

Back

The number of valence electrons corresponds to the group number of the element in the periodic table.
