Alkalis form acidic oxides so from d question its R dats d alkali cus it formed an acidic oxide. Tank me later 08164607938

Here's how we can break it down:
* Alkali metals are in the first group of the periodic table. They're known for forming basic hydrides and basic oxides.
Here's a clue from the question:
* R.H is a basic hydride. This tells us that R is likely an alkali metal.
Therefore, the answer is A. R.
Here's why the other options are less likely:
* Acidic hydrides are usually formed by non-metals.
* Atmospheric Oxides can be formed by many types of elements.
* XO2 is a formula that can be formed by many different elements.

alkali are oxides or hydroxides of metals that are soluble in water

it is amphoteric oxide not atmospheric oxide
