Answer 2

A noble gas is an atom with a full outer shell of electrons; unlike for example oxygen which has 2 spaces for other electrons to bond (like hydrogen in water - H20) noble gasses don't do a lot; the only one that reacts with anything in particular is Xenon; and even then its not a great reaction, they are colourless; odourless, inert (don’t do a lot) some are radioactive; but I cannot remember what ones.
The noble gas most people are familiar with is helium – balloons and Mickey Mouse, although argon is used in light bulbs; it doesn’t burn the filament as oxygen does. Most gases are extracted from the air; by cooling it down so oxygen, nitrogen etc are liquid or frozen and the gasses can be extracted. Except helium which is often extracted from oil; due to alpha radiation (basically a helium nucleus without electrons) getting stuck in oil deposits.

Answer 3

Describe Noble Gases

Answer 4

The noble gases are the chemical elements in group 18 (old-style Group 0) of the periodic table. This chemical series contains helium, neon, argon, krypton, xenon, and radon

.They have little tendency to gain or lose electrons. The noble gases have high ionization energies and negligible electronegativities.

Noble gases have full valence electron shells

The name 'noble gases' is an allusion to the similarly unreactive Noble metals, so called due to their preciousness, resistance to corrosion and long association with the aristocracy.

Answer 5

Noble gases have full valence electron shells. Valence electrons are the outermost electrons of an atom and are normally the only electrons which can participate in chemical bonding. According to atomic theory derived from quantum mechanics and experimental trends, atoms with full valence electron shells are extraordinarily stable and therefore do not form chemical bonds
The noble gases' lack of reactivity can be explained in terms of them having a "complete valence shell". They have little tendency to gain or lose electrons. The noble gases have high ionization energies and negligible electronegativities

Answer 6

noble gas
Any of the six chemical elements that make up the rightmost group of the periodic table as usually arranged: helium, neon, argon, krypton, xenon, and radon. All are colourless, odourless, and nonflammable and occur in tiny amounts in the atmosphere (though helium is the most plentiful element in the universe). Their stable electronic configurations, with no unpaired electrons to share, make them extremely unreactive-hence “noble” (i.e., aloof) or inert-though the three heaviest, with outer electrons held less firmly, can form compounds (mainly with fluorine). These gases absorb and give off electromagnetic radiation in a much less complex way than other substances, a property exploited in their use in fluorescent lighting devices and discharge lamps. They glow with a characteristic colour when confined in a transparent container at low pressure with an electric current passing through it. Their very low boiling and melting points make them useful as refrigerants for low-temperature research (see cryogenics).

Answer 7

Hi. Chemistry, eh? The noble gasses have a "satisfied" outer electron shell. They do not "need" or "give" any electrons to other atoms. They are VERY hard to combine with other elements because of this.

Answer 8

Too noble to react with other elements. Have complete electron set that fills their outer shells of eight electrons. They are in group 8A. Oh and they're all nonmetals. And they are gases at room temperature.

:)

Answer 9

The noble gasses are characterized by completely filled outer electron shell making them extremely non-reactive, since they do not need to borrow an electron to fill their shell, but also hold their electrons tightly.

Answer 10

Gases with 8 valence electrons, thaeytherefore have no desire to bond with other elements, since they're valence shell is filled.

Answer 11
