Noble gases don't usually react with other elements because they have a complete outer shell - they've already got all the valence electrons they need.
Atoms of elements in group 18 (noble gases) do not easily combine with other elements to form compounds.
Noble gases does not easily combine with other elementsbecause they are stable and have complete outermost shell.
Helium, neon, and argon are the only elements that exist in nature as isolated atoms, due to their stable electronic configurations that do not readily form chemical bonds with other elements. These elements are known as noble gases for their inert nature.
Noble Gases: Because Noble Gases are already in a stable form, they are not as likely to bond with other atoms as are those farther from a stable form. Noble Gases are found in group VIII, which is the far rightmost column.
Because noble gases were not discovered when Mendeleev formulated his periodic table
The noble gases in group 18 are inert.
Atoms of elements in group 18 (noble gases) do not easily combine with other elements to form compounds.
Noble gases does not easily combine with other elementsbecause they are stable and have complete outermost shell.
Atoms try to imitate the noble gases in the periodic table by changing their electrons. Noble gases have stable electron configurations, so other atoms will gain, lose, or share electrons in order to achieve a similar stable configuration like the noble gases.
Solids have tightly packed atoms so there is no space for the atoms to mingle. But in liquids/ gases, the atoms are more spread out and more free to move hence allowing the atoms to mingle.
The column all the way to the right of the periodic table indicates noble gases. Noble gases have their outermost orbit completely filled with electrons so these gases do not react with other things very easily. Some examples of noble gases are helium, radon, xenon etc.
8a group is the group in which the atoms "try to be like."
Helium, neon, and argon are the only elements that exist in nature as isolated atoms, due to their stable electronic configurations that do not readily form chemical bonds with other elements. These elements are known as noble gases for their inert nature.
Ther are no available electrons in any orbitals that are available for bonding
Lithium is not the largest atom. Atoms increase in size as you move down a column in the periodic table, so atoms in the bottom row (such as the noble gases) are generally larger than lithium.
Noble gases such as helium, neon, argon, krypton, and xenon exist as single atoms not bonded to other atoms. They are stable with a full outer electron shell, making them unreactive and existing as individual atoms in their natural state.
Noble Gases: Because Noble Gases are already in a stable form, they are not as likely to bond with other atoms as are those farther from a stable form. Noble Gases are found in group VIII, which is the far rightmost column.
