Purposeful Design Chapter 2.1

Front

What are transition metals?

Back

Transition metals are elements that have partially filled d orbitals and can form variable oxidation states. They are found in the d-block of the periodic table.

Front

Do transition metals contain valence electrons in only one shell?

Back

False. Transition metals have valence electrons in more than one shell.

Front

What properties do most metals possess?

Back

Most metals are malleable, ductile, and good conductors of heat and electricity.

Front

What two elements combine with metals to create a majority of the ores in Earth's crust?

Back

Oxygen and silicon.

Front

What is the actinide series?

Back

The actinide series consists of 15 elements from actinium to lawrencium, many of which are radioactive and synthetic.

Front

How many valence electrons do alkaline-earth metals have?

Back

Alkaline-earth metals have two valence electrons.

Front

What is malleability?

Back

Malleability is the ability of a material to be deformed under compressive stress, allowing it to be hammered or rolled into thin sheets.

Front

What is ductility?

Back

Ductility is the ability of a material to stretch or deform under tensile stress, allowing it to be drawn into wires.

Front

What are good conductors of heat and electricity?

Back

Materials that allow heat and electricity to flow through them easily, such as metals like copper and aluminum.

Front

What is a synthetic element?

Back

A synthetic element is an element that is not naturally occurring and is created artificially in a laboratory.
