Bohr & Lewis Models

Front

What is the Bohr Model of the atom?

Back

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

Front

What does a Lewis Dot Diagram represent?

Back

A Lewis Dot Diagram represents the valence electrons of an atom, showing the symbol of the element surrounded by dots that represent the valence electrons.

Front

What is the atomic number of an element?

Back

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

Front

What is the significance of groups in the Periodic Table?

Back

Groups in the Periodic Table are vertical columns that categorize elements with similar chemical properties and the same number of valence electrons.

Front

How many valence electrons does oxygen have?

Back

Oxygen has 6 valence electrons.

Front

What is the difference between the Bohr Model and the Lewis Dot Diagram?

Back

The Bohr Model shows all particles in an atom and their arrangement, while the Lewis Dot Diagram focuses only on the valence electrons.

Front

What is a dot diagram?

Back

A dot diagram is a visual representation of an atom's valence electrons, typically used in Lewis Dot Diagrams.

Front

What is the role of neutrons in an atom?

Back

Neutrons are neutral particles found in the nucleus of an atom that contribute to the atomic mass but do not affect the charge.

Front

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

Back

The maximum number of electrons in the first energy level is 2.

Front

What is the relationship between the number of protons and electrons in a neutral atom?

Back

In a neutral atom, the number of protons equals the number of electrons, balancing the positive and negative charges.
