Argon is found in the form of 3 isotopes: 40Ar, 36Ar and 38Ar (in order of abundance). All three are stable.
argon's physical properties are: gas or liquid forms colorless/odourless/ tasteless :)
they share electrons with the other atom they're combining with
Argon is a stable, inert gas and does not react with other elements. Calcium is a reactive metal, particularly with water and acids, but it forms stable compounds like calcium oxide and calcium carbonate.
Xenon has a hexafluoride, which is xenon hexafluoride (XeF6). Argon does not have a stable hexafluoride compound.
No. Argon is a nonmetal, and furthermore, a gas.
It forms a small part (0.934%) of air, by volume.
No bond forms between hydrogen and argon because they belong to different groups on the periodic table. Hydrogen typically forms covalent bonds with other elements, while argon is a noble gas that exists as individual atoms.
Argon is a noble gas, not a metal. It is a colorless, odorless, and inert gas at room temperature and forms a gas in its elemental state.
When oxygen reacts with argon, it forms argon oxide compounds such as argon(II) oxide (ArO) or argon(IV) oxide (ArO2). These compounds are unstable and tend to decompose easily. This reaction is not commonly observed under normal conditions as argon is generally inert and does not readily react with other elements.
Hexafluoride compounds are formed when oxygen combines with either argon or xenon in the presence of fluorine. These compounds have the chemical formula XeF6 for xenon and ArF6 for argon.
When sulfur forms a negative ion, it gains two electrons to achieve a full outer electron shell, making it have the same electron configuration as argon.
Probably fluorine.
