Noble gases differ from other elements in that the number of electrons that are attached to the core is exactly right. Most elements have either too much or too few electrons to fill their shells (rings of electrons surrounding the nucleus). Noble gasses therefore do not interact with other elements to shed, share or steal electrons like other elements do.
Under normal conditions these gases do not react with any other element, and it is therefore that no one ever isolated a noble gas until 1895.
A full octet makes the noble gases nonreactive.
Group 18 is often referred to as the Noble Gases.
Fluorine can form compounds with every element except Helium. Many compounds with the noble gases (such as neon fluoride) are pretty unstable and most are very reactive, but they can be formed.
It is the same for each and every element, it's the number of protons in the nucleus of one atom of the element.
Each element has a different number of neutrons.
noble gases. You"re welcome.
Noble gases have completely filled octet. It makes it difficult to get unstable.
Noble Gases have a complete set of electrons in their orbits. As seen in a Bohr Diagram, there can by two electrons in the first orbit, eight in the next two, and eighteen in the next two. When an entire orbit is filled perfectly (2 in Helium, 10 in Neon, 18 in Argon, etc.), the element is very stable and, thus, a "Noble Gas."

I assume that you mean Helium ... one of the Noble Gases. It is the second lightest Element, Hydrogen is the first. Being a noble gas, it does not burn so it is used in balloons. The noble gases do not readily combine with other elements to form other compounds ... they just 'stand alone.' A balloon filled with hydrogen can and does easily explode, but one filled with helium will not
If the question is what classifies and element as a noble gas, then the answer is that they have a full octet of valence electrons. This makes them more stable and less likely to react, the noble gases can be found on the last period (or vertical column) on the periodic table.
It's fullfill electronic configuration i.e ns2np6 configuration.
Any of the noble gases. This can be Helium, Neon, Argon, Krypton, Xenon or even Radon. Neon, for example, makes red. Krypton makes a blue colour.
These gases are nitrogen, oxygen, argon, other noble gases, carbon dioxide, water vapors.
