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.

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.

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
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
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
This family of elements display properties of both metals and non-metals. For example, metals are good conductors and non-metals are poor conductors. This means that they are semiconductors (only conducts electricity at high temperatures.).
(a)
This elements also known as “salt formers” in Greek. This is evident in nature as salts interact with metals to form various salts. On another note, the halogens are a unique group of elements. They are the only periodic family that contains elements in the three states of matter at standard temperature. There are 6 of them identified and they are located in group 17. These elements include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They are highly reactive, highly electronegative, and highly toxic non-metals
(a)
Also called aerogens, are inert gases. Some examples include argon, krypton, and neon. They can be found in group eighteen on the periodic table. Likewise, this means they have a complete valence shell. For this reason, they are stable and relatively unreactive. Furthermore, the noble gases have low boiling points and low melting points. Physically they are colorless and have no smell.
(a)
Latin name for SILVER which means "white" or "shining"

Bonus Question for 2 points.
N2O or the Nitrous Oxide it has a euphoric effect when inhaled. It has a mildly sweet odor and taste. This compound is also known as (a) gas.
