Bohr Models Challenge (Warm-Up)

Front

What is a Bohr Model?

Back

A Bohr Model is a diagram that represents the arrangement of electrons in an atom, showing the energy levels and the number of electrons in each level.

Front

How many electrons can the first energy level hold in a Bohr Model?

Back

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

Front

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

Back

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

Front

How many electrons can the third energy level hold in a Bohr Model?

Back

The third energy level can hold a maximum of 18 electrons, but typically holds 8 for the first 18 elements.

Front

What element has 2 electrons in the first energy level and 8 in the second?

Back

Neon.

Front

What element has 2 electrons in the first energy level, 8 in the second, and 2 in the third?

Back

Magnesium.

Front

What element has 2 electrons in the first energy level, 8 in the second, and 5 in the third?

Back

Phosphorus.

Front

What element has 2 electrons in the first energy level and 6 in the second?

Back

Oxygen.

Front

What is the main difference in the Bohr Models of Lithium and Beryllium?

Back

Beryllium has one more electron in the outermost energy level than Lithium.

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.
