Bohr model

Front

What is the Bohr model?

Back

The Bohr model is a theory of atomic structure that depicts electrons orbiting the nucleus in fixed paths or energy levels.

Front

What does the atomic number represent?

Back

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

Front

What is a mass number?

Back

The mass number is the total number of protons and neutrons in an atom's nucleus.

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 electrons can the first energy level hold?

Back

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

Front

How many electrons can the second energy level hold?

Back

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

Front

What is the significance of the group number in the periodic table?

Back

The group number indicates the number of valence electrons in the elements of that group, which affects their chemical properties.

Front

What is the electron configuration of Neon?

Back

The electron configuration of Neon is 1s² 2s² 2p⁶.

Front

What is the relationship between energy levels and distance from the nucleus?

Back

Energy levels are further from the nucleus as they increase, meaning electrons in higher energy levels are farther away from the nucleus.

Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net charge.
