An element X forms two oxides XO and `XO_(2)`. The oxide XO is neutral but `XO_(2)` is acidic in nature. The element X iis most likely to be:

An element X forms two oxides XO and XO_(2) . The oxide XO has no action litmus solution but oxide XO_(2) turns litmus solution red. (a). What is the nature of oxide XO? (b). What is the nature of oxide XO_(2) ? (c). Would you call element X a metal or a non-metal? Give reason for you choice. (d). Can you give an example of element like X?

An element (X) when burnt in oxygen forms neutral XO and acidic XO_(2) . The element X is

An element 'X' forms an oxide XO_(2) , which is a very useful gas used in photosynthesis process. The element is

(i) A non-metal X exists in two different forms Y and Z. Y is the hardest natural substance whereas Z is a good conductor of electricity. Identify X, Y, Z. (ii) A element, X, on reaction with oxygen forms an oxide XO_(2) . The Oxide when dissolved in water turns blue litmus red. State whether element X is a metal or a non-metal. (ii) Name the metal which is alloyed with copper to make bronze.
