These gases very rarely react, with others and also noble gases are odourless and colourless.
Explanation:
- Noble gases will not react with anything so that is the reason why they are known as an inert gas.
- Noble gases are present in group 18 on the periodic table and following the rule of the octet which is they completed their orbital by s2p6 which is the highest energy level.
- Most elements are discovering through their reactivity with the other elements, commonly with oxygen. In the case of a noble gas, it is difficult for a scientist to work with the gases which have very less or no chemical property in terms of their reactivity.
The ions are as follows;
- As2O3 - As^3+, O^2-
- MnS - Mn^2+, S^2-
- VCl3 - V^3+, Cl^-
- NiF2 - Ni^2+, F^-
<h3>What is a cation and an anion?</h3>
A cation is a positive ion while an anion is a negative ion. Ionic compounds are composed o cations and anions.
The anions and cations in the ionic compounds in the table are shown below;
- As2O3 - As^3+, O^2-
- MnS - Mn^2+, S^2-
- VCl3 - V^3+, Cl^-
- NiF2 - Ni^2+, F^-
