Bohr Models

Front

What is a Bohr Model?

Back

A Bohr Model is a diagram that represents the structure of an atom, showing electrons in specific energy levels around the nucleus.

Front

How many electrons can the first energy level hold?

Back

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

Front

How many electrons can the second energy level hold?

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 shell of an atom that are involved in chemical bonding.

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.

Front

What is the significance of valence electrons in chemical reactions?

Back

Valence electrons determine how an atom will bond with other atoms, influencing the chemical properties of the element.

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which also determines the element's identity.

Front

What is the relationship between periods and energy levels in the periodic table?

Back

Each period in the periodic table corresponds to a new energy level for the electrons.

Front

What is the difference between groups and periods in the periodic table?

Back

Groups are vertical columns that contain elements with similar properties, while periods are horizontal rows that indicate the number of energy levels.

Front

What element has 8 valence electrons?

Back

Noble gases, such as Neon and Argon, have 8 valence electrons.
