Bohr Models

Front

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 atom?

Back

Valence electrons can be determined by the group number of the element in the periodic table; for main group elements, the group number corresponds to the number of valence electrons.

What is a Bohr model?

Back

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

Front

What is the maximum number of electrons that can occupy the first energy level in a Bohr model?

Back

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

Front

What is the maximum number of electrons that can occupy the second energy level in a Bohr model?

Back

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

How does the position of an element in the periodic table relate to its properties?

Back

The position of an element in the periodic table indicates its atomic structure, including the number of protons, neutrons, and electrons, which in turn influences its chemical properties.
