Unit 04 Review - Electrons - 4 Bohr Diagrams - 531/532

Front

What is a Bohr diagram?

Back

A Bohr diagram is a visual representation of an atom that shows the arrangement of electrons in different energy levels around the nucleus.

Front

What does the atomic number represent?

Back

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

Front

How do you determine the number of protons in an atom?

Back

The number of protons in an atom is equal to the atomic number of the element.

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 many valence electrons does Aluminum (Al) have?

Back

Aluminum has 3 valence electrons.

Front

What is the significance of inner-shell electrons?

Back

Inner-shell electrons are those that are not involved in bonding and help shield the outer electrons from the nucleus's positive charge.

Front

How many inner-shell electrons does an atom with 16 protons have?

Back

An atom with 16 protons (Sulfur) has 8 inner-shell electrons.

Front

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

Back

The maximum number of electrons in the first energy level is 2.

Front

What is the maximum number of electrons in the second energy level?

Back

The maximum number of electrons in the second energy level is 8.

Front

How do you calculate the total number of electrons in an atom?

Back

The total number of electrons in a neutral atom is equal to the number of protons.
