This is the group 18, noble gases.
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.
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 column on the far left of the periodic table contains the alkali metals. These elements are highly reactive and have one electron in their outer shell. They include elements such as lithium, sodium, and potassium.
Column 18, or in older tables, column VIII, the noble gases.
Representative elements
The column that contains elements whose electron configuration ends with d4 is the "transition metals" column. Transition metals have partially filled d orbitals in their electron configurations, typically with the d orbitals being filled first before the s and p orbitals.
A column in the periodic table is called a group or a family. Elements within the same group share similar chemical properties due to having the same number of valence electrons. There are 18 groups in the periodic table.
The Alkali Metals are the first column of the periodic table, except for Hydrogen.
The right-most column of the periodic table contains Heliu, Neon, Argon, Kryton, Xenon, Radon, and Ununoctium. All these elements are in the noble gas group. All of these elements are classified as non-metallic.
First off, there is no "salt" on the periodic table of the elements. Salt is a compound. However, you may be talking about "sodium". If that's the case, sodium is NOT in the same column as oxygen in the periodic table. Sodium is in the first column while oxygen is in the sixteenth column.
The elements in column 18 of the periodic table, also known as the noble gases, all have a full outer electron shell, making them stable and unreactive. This is because their outer shell is filled with electrons, so they do not typically form chemical bonds with other elements.
Elements in the same column have similar chemical properties. They are from the same family.
