You might be referring to the metals whose oxides are amphoteric-can behave either as acids or bases. There are many of these, including zinc and aluminum.
For more about this subject see the wikipedia article about amphoterism.
When a metal reacts with oxygen, it forms a metal oxide which is basic in nature. This can be distinguished from a non-metal oxide, which is acidic in nature. This difference in the nature of oxides can be used to identify whether a substance is a metal or non-metal.
Non-metal oxides are typically covalent compounds that form when a non-metal reacts with oxygen. They tend to be acidic in nature, as they form acids when they dissolve in water. Examples include carbon dioxide (CO2) and sulfur dioxide (SO2).
as blue litmus turns red the compound is an acid. Non metal oxides are acidic in nature. Thus the the element 'X' is a non metal.
Metal oxides are basic in nature, not acidic or alkaline. They react with acids to form salts and water, displaying typical basic behavior.
Metal oxides can act as bases because of their ability to accept protons. When metal oxides react with water, they can form metal hydroxides, which are basic in nature due to their ability to release hydroxide ions in solution.

Yes, P2O5 is an acidic oxide. When it reacts with water, it forms phosphoric acid, which is a strong acid, making P2O5 acidic in nature.
Nitrogendioxide
Nitric oxide is considered a neutral oxide, as it does not exhibit distinct basic or acidic properties. It reacts with both acids and bases to form different compounds.
as blue litmus turns red the compound is an acid. Non metal oxides are acidic in nature. Thus the the element 'X' is a non metal.

When a non-metal oxide, such as sulfur dioxide, is dissolved in water, it forms an acidic solution. This is because non-metal oxides react with water to produce acids.
When a metal oxide is dissolved in water, it typically forms a basic solution. In this case, blue litmus paper will remain blue, indicating the basic nature of the solution. If the metal oxide were to produce an acidic solution, red litmus paper would turn blue, but this is less common for metal oxides.
Non-metal oxides are compounds that contain a non-metal element bonded with oxygen. They tend to be acidic in nature and can react with water to form acids. Non-metal oxides play a role in atmospheric chemistry and can contribute to acid rain when they dissolve in water droplets.
