The ground state of Oxygen contains only eight electrons in only the first two energy levels.
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.
Elements in the same family have similar chemical properties because they have the same number of outer electrons, which determines their reactivity. This similarity is due to the elements in a family occupying the same column on the periodic table, which means they share the same number of valence electrons.
Elements in family 1 (alkali metals) are highly reactive, readily losing electrons to form cations with a +1 charge. Elements in family 18 (noble gases) are inert and have very low reactivity because they have a full outer electron shell, making them stable and unlikely to form chemical bonds.
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.
Noble gases, such as helium and neon, belong to the family of elements that are highly unreactive. They have a full outer electron shell, making them stable and less likely to form chemical bonds with other elements.
The family of elements with two electrons in its outer energy level is the alkaline earth metals. This group includes elements like beryllium, magnesium, calcium, strontium, and barium. These elements are highly reactive and tend to form 2+ cations by losing their two outer electrons.
This is the noble gases familiy.
Such atoms belong to a group in the periodic table of elements.
The column on the periodic table that contains elements with completely filled outer energy levels is the noble gases column (group 18 or Group 8A). These elements have a full outermost energy level, making them stable and less likely to form bonds with other elements.
This is the group 18, noble gases.
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.
The three elements in the family that produce a magnetic field are iron, cobalt, and nickel. These elements have unpaired electrons in their outer energy levels, which allows them to align their spins and create a magnetic field.
The outermost shell contains two electrons.
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.
