Bohr Models Challenge (Warm-Up)

Front

What is a Bohr model?

Back

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

Front

What element is represented by the Bohr model with 16 protons?

Back

Sulfur.

Front

How many energy levels does the Bohr model of Calcium have?

Back

4 energy levels.

Front

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

Back

2 electrons.

Front

How many electrons can the second energy level hold in a Bohr model?

Back

8 electrons.

Front

What is the definition of 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 valence electrons does carbon have?

Back

4 valence electrons.

Front

If an element has 2 electrons in the first energy level, 8 in the second, and 3 in the third, how many valence electrons does it have?

Back

3 valence electrons.

Front

What is the significance of the outermost energy level in a Bohr model?

Back

The outermost energy level determines the chemical properties and reactivity of the element.
