why are noble gases called group 0?
17712
The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.

Noble gases are monoatomic, which means they exist as single atoms. This is because of their electronic stability. Unlike most common gases that exist as diatomic molecules like O2, N2, and Cl2, the noble gases exist as single atoms like He, Ne, Ar, i.e. they are monatomic molecules.

The noble gases are relatively nonreactive. In fact, they are the least reactive elements on the periodic table. This is because they have a complete valence shell. ... The noble gases have low boiling points and are all gases at room temperature.
557188
All of the elements in Group Zero are noble gases. The list includes helium, neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). ... They are not just rare in nature, but rare as useful elements, too.

Noble Gases They were once called inert gases because they were thought to be completely inert—unable to form compounds. This is a reasonable belief because the noble gases have a complete octet, making them very stable and unlikely to gain or lose any electrons.

The noble gases all have low boiling points : ... boiling point increases going down the group.
1207459
All noble gases have full s and p outer electron shells (except helium, which has no p sublevel), and so do not form chemical compounds easily. Their high ionization energy and almost zero electron affinity explain their non-reactivity. ... The first binary noble gas compounds were reported later in 1962.

Noble gas. 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.
1429236
Noble gases like He, Ne, Kr, Xe and Rn are placed in a separate group because of the following reasons: - They are extremely unreactive. - They donot combine with any other element of the periodic table. - All the noble gas elements have zero valency and placed in zero group with similar chemical properties.

A noble gas is different from other elements because its highest electron energy level is completely filled. The examples of noble gases are helium, neon, Argon , krypton,Xenon , radon.
550547
Because noble gases' outer shells are full, they are extremely stable, tending not to form chemical bonds and having a small tendency to gain or lose electrons. ... Overall, noble gases have weak interatomic forces, and therefore very low boiling and melting points compared with elements of other groups.

Group 0 contains non-metal elements placed in the vertical column on the far right of the periodic table . The elements in group 0 are called the noble gases . They exist as single atoms .

Noble gases are the elements that belong respectively to group 18 . What do they all have in common? Well, since they are the very last group on the periodic table, they have full outer shells of valence electrons.
610821
Neon, along with helium, argon, krypton and xenon, make up the group known as noble gases. These are the most stable and least reactive elements due to having full valence shells (the outer shell has the max number of electrons, two for helium, eight for the rest).

The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the "inert gases" due to the fact that their filled valence shells (octets) make them extremely nonreactive.
1037651
The group 18 elements include helium, neon, argon, krypton, xenon and radon. They are referred to as noble gases or inert gases.
