Families of the Elements in the Periodic Tables

A chemical element with the symbol Au from Latin word Aurum. It is attractive in color and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form. Identify the described Element.

There are 118 total recorded elements in our periodic table. How many elements occur naturally?

What do you call element which are groups of elements with similar properties. These are alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, halogens, noble metals, and noble gases.

• Periods

• Families

• Group

• Atomic Mass

They consist of all of the elements in group one with the exception of hydrogen. These elements are extremely reactive and for this reason, are usually found in compounds. In addition, they are water-sensitive (they react violently with water), so they must be stored in oil.

• Transition Metals

• Halogens

• Alkaline Metals

• Alkali Metals

NGSS.MS-PS1-2

NGSS.MS-PS1-5

The second most reactive family on the periodic table (following behind the alkali metals). Moreover, they are strong reducing agents which means they donate electrons in chemical reactions. They are also good thermal and electrical conductors. Physically, they have low density, low melting point, and a low boiling point.

• Transition Metals

• Halogens

• Alkaline Earth Metals

• Alkali Metals

They are known as Rare-Earth Metals.

• Metals and metalloids

• Semiconductor and superconductors

• Actinides and Lanthanides

• Noble Gases

NGSS.MS-PS1-1

NGSS.MS-ESS3-1

They typically form two or more oxidation states. They have low ionization energies and high conductivity. In addition, they have high melting points, high boiling points, and high conductivity. Physically they are both metallic and malleable.

• Transition Metals

• Metalloids

• Alkali Metals

• Actinides
