The ground state of Oxygen contains only eight electrons in only the first two energy levels.
Noble Gases.
S8 or sulphur
Elements in the same family (or group) have the same amount of electrons in their outer shell. For Example, all elements in Group 1 have 1 electron in their outer shells.
This is the noble gases familiy.
Such atoms belong to a group in the periodic table of elements.
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
Elements react with other elements based on the number of electrons in their outer shell, also called valence electrons.
Elements in the same family (or group) have the same amount of electrons in their outer shell. For Example, all elements in Group 1 have 1 electron in their outer shells.
All elements in the oxygen family have 6 electrons in the outer orbit.
This is the noble gases familiy.
They are the alkaline metals.
Such atoms belong to a group in the periodic table of elements.
All the elements in the Inert Gases family (exc. Radon) are highly unreactive. The Inert Gases family occupies Group 18(0) of the Periodic Table. They each have 8 electrons in the outer shell. The Inert Gases Group contains;HeliumNeonArgonKryptonXenonRADON

Group 18 or the noble gases.
This is the group 18, noble gases.
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
The outer energy shells in the group 18 elements, called the noble gases, have a complete octet of ns2np6, where n is the highest energy level. The only exception is helium, which has an outer energy shell of 1s2.
That is correct; the first column on the left contains only elements with one electron in their outer shell, also known as "valance electrons". This column is referred to as Group 1, also known as the Alkali Metals.
