Bohr Models and Lewis Dot Diagrams

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 many electrons does Silicon (Si) have?

Back

Silicon (Si) has 14 electrons.

Front

How many valence electrons does Chlorine (Cl) have in its Lewis dot model?

Back

Chlorine has 7 valence electrons in its Lewis dot model.

Front

How many valence electrons does Nitrogen (N) have in its Lewis dot model?

Back

Nitrogen has 5 valence electrons in its Lewis dot model.

Front

What is a Bohr model?

Back

A Bohr model is a diagram that represents an atom with a nucleus surrounded by electrons in specific energy levels.

Front

What is a Lewis dot diagram?

Back

A Lewis dot diagram is a representation of an atom that shows its valence electrons as dots around the element's symbol.

Front

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

Back

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

Front

What is the significance of valence electrons?

Back

Valence electrons are important because they determine how an element will react chemically with other elements.

Front

What is the maximum number of electrons in the first energy level of an atom?

Back

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

Front

What is the maximum number of electrons in the second energy level of an atom?

Back

The maximum number of electrons in the second energy level is 8.
