Bohr Models Challenge (Warm-Up)

Front

What is the Bohr Model of an atom?

Back

The Bohr Model is a representation of the atom that depicts electrons orbiting the nucleus in defined energy levels or shells.

Front

How many electrons can the first energy level of an atom hold?

Back

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

Front

What is the maximum number of electrons that can occupy the second energy level?

Back

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

Front

What are 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 Lithium have?

Back

Lithium has 1 valence electron.

Front

What is the significance of an element's group number in the periodic table?

Back

The group number indicates the number of valence electrons in the outermost shell of the elements in that group.

Front

How many valence electrons does Chlorine have?

Back

Chlorine has 7 valence electrons.

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 also determines the number of electrons in a neutral atom.

Front

How many energy levels does Calcium have in its Bohr Model?

Back

Calcium has 4 energy levels in its Bohr Model.

Front

What is the Bohr Model for Fluorine, Atomic Number = 9?

Back

Fluorine has 2 electrons in the first energy level and 7 electrons in the second energy level.
