Bohr Models & Configurations

Front

What is the Bohr model?

Back

The Bohr model is a representation of the atom that depicts electrons orbiting the nucleus in fixed paths or energy levels.

Front

What are energy levels in an atom?

Back

Energy levels are the fixed distances from the nucleus where electrons can be found, each level can hold a specific maximum number of electrons.

Front

How many electrons can the first energy level hold?

Back

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

Front

What are valence electrons?

Back

Valence electrons are the electrons located in the outermost energy level of an atom, important for chemical bonding.

Front

What group do alkali metals belong to?

Back

Alkali metals belong to Group 1 (1A) of the periodic table.

Front

What group do halogens belong to?

Back

Halogens belong to Group 17 (7A) of the periodic table.

Front

What are noble gases?

Back

Noble gases are elements in Group 18 (8A) that are characterized by their lack of reactivity due to having a full outer electron shell.

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 significance of the atomic number?

Back

The atomic number indicates the number of protons in an atom's nucleus and determines the element's identity.

Front

What is an electron configuration?

Back

An electron configuration is the distribution of electrons among the various energy levels and orbitals in an atom.
