Because all noble gases have completely filled valence orbitals. Helium has 2 valence electrons whereas all other noble gases have 8 valence electrons.
if u put fire by it maby I dont really know, do you?
Noble Gases are not reactive elements, no compounds are known for He or Ne. The heavier ones can form unstable compounds. Xenon and Krypton have a number of well known reactive fluorides and oxyfluorides.
Noble gases have a full valence shell of electrons, so they are stable and do not readily gain or lose electrons. This stability leads to very low electron affinity values for noble gases, as they do not have a strong tendency to attract additional electrons to achieve a more stable electron configuration.
Noble gases are used in lights because they are inert and do not react with other elements, making them stable and safe. When electricity passes through the gases, they emit colorful light due to the energy released during the process. This makes noble gases like neon, argon, and xenon popular choices for creating bright and vibrant lighting displays.
Noble gases can be made visible by either using a discharge tube to apply an electric current, causing them to emit colored light, or by forming compounds with other elements that exhibit color. For example, xenon can produce a blue glow when electrically excited, and radon can form compounds that emit visible light.

The noble gases at the very right column of the Periodic Table. They have full outer electron shells, so there is no need to form covalent or ionic bonds. Radon and Xenon however, have been made, with difficulty, into compounds in recent years.
Yes they do. For abbreviated notation you should not just put the noble gas in brackets and call it done... back it up to the previous noble gas. For instance: Argon: 1s2 2s2 2p6 3s2 3p6 or [Ne] 3s2 3p6
yes because they have same effects

You put lots of people in a contact group and send to that group.

We all know that helium is a noble gas. It has atomic number 2 but it is placed in 18 group be because in 1st group the elements have only one electron in thier s orbital e.g. Hydrogen, lithium, sodium, potassium etc. But helium has two electron so it cannot exist in 1 group. In second group the s orbital are same but the physical and properties of helium is different from the elements present in second group. According to modern periodic table elements which have same physical properties are placed in same group. Since helium is an inert gas and its physical properties are similar to the other elements of the 18 group and also helium discoverd late so that hilium can be put in the 18 group
If it's the same group size & terminals.
