Magic of Electrons Lesson 1.1 Review Game

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

How many valence electrons does an atom with 8 valence electrons have?

Back

8

Front

Which elements are in the same group in the periodic table?

Back

Elements in the same group have similar chemical properties and the same number of valence electrons.

Front

What happens if you place an insulator in an open circuit?

Back

It will not allow electricity to flow.

Front

Why do insulators not allow the flow of electricity?

Back

Insulators have tight electrons that do not move freely.

Front

What is a semiconductor?

Back

A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator.

Front

Give an example of a semiconductor.

Back

Germanium is an example of a semiconductor.

Front

What is the difference between metals, metalloids, and non-metals?

Back

Metals are good conductors of electricity, metalloids have properties of both metals and non-metals, and non-metals are poor conductors.

Front

What are the properties of metalloids?

Back

Metalloids are shiny, brittle, and semi-conductive.

Front

What is the significance of the periodic table groups?

Back

Elements in the same group have similar chemical properties and reactivity.
