Bohr and Lewis Dot Models

Front

What is the Bohr model of the atom?

Back

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

Front

What is a Lewis dot model?

Back

A Lewis dot model represents the valence electrons of an atom as dots around the element's symbol.

Front

How many energy levels does Calcium (Ca) have?

Back

Calcium has 4 energy levels.

Front

What is the Octet rule?

Back

The Octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

How many valence electrons does Chlorine (Cl) have?

Back

Chlorine has 7 valence electrons.

Front

How many electrons should Potassium (K) have in its Lewis dot model?

Back

Potassium should have 1 electron in its Lewis dot model.

Front

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

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?

Back

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

Front

What is the significance of valence electrons?

Back

Valence electrons determine how an atom can bond with other atoms.

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.
