Flashcardizz Practice Unit 4 Lesson 1

Front

What is an ion?

Back

An ion is an atom that has gained or lost one or more electrons, resulting in a net positive or negative charge.

Front

How many valence electrons does an atom with a full outer shell have?

Back

An atom with a full outer shell has 8 valence electrons.

Front

What do Lewis Dot Diagrams represent?

Back

Lewis Dot Diagrams simplify the Bohr Model by showing only the outer valence electrons used for bonding.

Front

What are the rows on the periodic table called?

Back

The rows on the periodic table are called periods.

Front

What are the columns on the periodic table called?

Back

The columns on the periodic table are called groups.

Front

What element has 6 valence electrons and is represented by the symbol 'O'?

Back

The element is Oxygen (O).

Front

What is the significance of valence electrons?

Back

Valence electrons determine how an atom can bond with other atoms.

Front

What is a Bohr Model?

Back

A Bohr Model is a diagram that represents an atom with electrons in defined orbits around the nucleus.

Front

What is the difference between isotopes and ions?

Back

Isotopes are atoms of the same element with different numbers of neutrons, while ions are atoms that have gained or lost electrons.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined from the element's group number in the periodic table.
