What are the 8 noble gases?

The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).

The six noble gases that occur naturally are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).

Hydrogen is classified as a non-metal based on its physical properties. All elements in group one have one valence electrons, as does hydrogen. In terms of its chemical reactions hydrogen can form both covalent and ionic bonds. It bonds covalently with other non-metals such as nitrogen, sulfur, oxygen, carbon, etc.

The only chemical elements which are stable single atom molecules at standard temperature and pressure (STP) are the noble gases. These are helium, neon, argon, krypton, xenon and radon. Noble gases have a full outer valence shell making them rather non-reactive species.

Neon is a chemical element with symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.

The noble gases are used in industry in arc welding, to dilute the oxygen in deep-sea divers’ gas tanks, and to fill light bulbs. Argon is used in arc welding and in common light bulbs, as it does not react with the metal at high temperatures.

The group consists of yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium).

These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).

As far as I know, the only inert gases are the noble gases such as argon, helium, neon, krypton and radon. Inert gases do not readily react with other elements to form compounds and hence their name. So oxygen is a very reactive gas and cannot be considered inert.

It is called a compound. It is also a pure substance like an element. For example sodium chloride is a compound of the two elements sodium and chlorine. Sulphuric acid is a compound of three elements, namely, sulphur, hydrogen and oxygen.

Nitrogen (N2) is a colorless, odorless and tasteless gas that makes up 78.09% (by volume) of the air we breathe. It is commonly thought of and used as an inert gas; but it is not truly inert. It forms nitric oxide and nitrogen dioxide with oxygen, ammonia with hydrogen, and nitrogen sulfide with sulfur.

The other tendency of atoms is to maintain a neutral charge. Only the noble gases (the elements on the right-most column of the periodic table) have zero charge with filled valence octets. All of the other elements have a charge when they have eight electrons all to themselves.

Argon is the third noble gas, in period 8, and it makes up about 1% of the Earth’s atmosphere. Argon has approximately the same solubility as oxygen and it is 2.5 times as soluble in water as nitrogen . This chemically inert element is colorless and odorless in both its liquid and gaseous forms.

This group lies in the d-block of the periodic table. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals. The three Group 4 elements that occur naturally are titanium, zirconium and hafnium.

Noble gas configuration is the electron configuration of noble gases. The basis of all chemical reactions is the tendency of chemical elements to acquire stability. For some main group elements, chemical bond formation often results in a complete electronic configuration resembling a noble gas.

The name argon comes from Greek and means ‘inert.’ It is important to know that not all inert gases are found in the periodic table because they are molecular gases. These include nitrogen gas (N2) and carbon dioxide (CO2).

The only chemical elements which are stable single atom molecules at standard temperature and pressure (STP) are the noble gases. These are helium, neon, argon, krypton, xenon and radon. The heavier noble gases can form chemical compounds, but the lighter ones are non-reactive or inert.
