Bohr Models

Front

What is the Bohr model of the atom?

Back

The Bohr model is a theory that describes the atom as having a central nucleus surrounded by electrons that travel in specific orbits or energy levels.

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons is determined by the group number of the element in the periodic table.

Front

What are valence electrons?

Back

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

Front

What element has the atomic number 2?

Back

Helium.

Front

What is the significance of valence electrons in chemical reactions?

Back

Valence electrons determine how an atom can bond with other atoms and participate in chemical reactions.

Front

How many total electrons can the third energy level hold?

Back

18.

Front

What is the relationship between energy levels and electron configuration?

Back

Energy levels determine the arrangement of electrons in an atom, which is described by its electron configuration.
