This video excerpt from NOVA's "Hunting the Elements" explains why some elements are more reactive than others. ... Noble gases have low reactivity because they have full electron shells.

The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore ...

For the first time, scientists have succeeded in the stabilisation and direct imaging of small clusters of noble gas atoms at room temperature. This achievement opens up exciting possibilities for ...

An Elemental Quiz. By Susan K. Lewis; Posted 09.01.06; NOVA scienceNOW; How well do you know your way around the periodic table? Can you tell a noble gas from neptunium?

Led by physicist Jani Kotakoski, the team obtained the images while studying how radiation modifies the properties of graphene (a sheet of carbon just one atom thick) and other two-dimensional ...

Noble gases—radon, xenon, krypton, argon, neon, and helium—are snobs. Their atoms typically shun liaisons with other elements because they already have all the electrons they need, but none to ...

In 1904 Sir William Ramsay won a Nobel Prize for discovering noble gases - and today Dr Andrea Sella shows how they light up the laboratory at University College London.

A noble gas is a specific set of elements that, under standard conditions, have very similar properties. Specifically, they are colorless, odorless and have very low chemical reactivity.
