The six noble gases: helium, neon, argon, krypton, xenon and radon
metal
Any use, radon is a radioactive and very dangerous gas !
The family of elements found in the human body, Earth's crust, and Earth's oceans primarily includes the major biogenic elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. These elements are essential for life and are prevalent in biological molecules, minerals, and seawater. Additionally, trace elements like potassium, sodium, magnesium, and sulfur are also important for various biological functions and are found in these environments.
The semi conducting elements are the metalloid. There is two metalloid in that column: Silicon and Germanium.
Elements in the same family (group) on the periodic table have the same number of valence electrons and hence they have similar properties and reactivities.

Californium is a member of the actinides group.
There are quite a few elements that do not normally react. These elements are all found in the Noble Gas family.
Europium belongs to the lanthanide family, also known as the rare earth elements. These elements are found in the f-block of the periodic table and share similar chemical properties.
Carbon is the only non-metal in carbon family. The other elements are either metalloids or metals.

No, the most stable elements on the periodic table are typically found in the noble gas family. Alkali metals, such as lithium and sodium, are relatively reactive compared to noble gases like helium and neon, which have full valence shells and are therefore more stable.
The halogen family of elements (fluorine, chlorine, bromine, iodine, and astatine) are found pretty much everywhere on Earth.
Cerium is an element that is found in the Earth's crust. Cerium is in the Lanthanide family which is made up of rare earth metals.

Halogens are in the group 17 of the periodic table of Mendeleev.
Phosphorous is found in group 15 on the Periodic Table of the Elements. This is called the Nitrogen group.
