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

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

Back

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

Front

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

Back

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

Front

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

Back

The third energy level can hold a maximum of 18 electrons, but typically holds 8 in the first 20 elements.

Front

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

Back

Oxygen.

Front

Which element has 2 electrons in the first energy level, 8 in the second, and 7 in the third?

Back

Chlorine.

Front

Which element has 2 electrons in the first energy level, 8 in the second, and 1 in the third?

Back

Sodium.

Front

What is the significance of the number of electrons in each energy level in a Bohr Model?

Back

The number of electrons in each energy level determines the chemical properties and reactivity of the element.

Front

What element does a Bohr model with 2 electrons in the first level, 8 in the second, and 2 in the third represent?

Back

Magnesium.

Front

What is the general rule for filling energy levels in a Bohr Model?

Back

Electrons fill the lowest energy levels first before moving to higher levels.
