Answer : The correct option is, \(As_2O_5\)
Explanation :
Diarsenic pentoxide having the formula, \(As_2O_5\). It is a covalent compound which is formed by the sharing of electrons between the two non-metals. The two non-metals are arsenic (As) and oxygen (O).
When the two arsenic atoms share their electrons to the five oxygen atoms to form \(As_2O_5\) covalent compound.
The formula of covalent compound is given by :
- The less electronegative element is written first.
- The more electronegative element is written second.
- If the prefixes are written with the elements then the prefix number is written in the subscript of the respective elements.
Hence, the formula for diarsenic pentoxide is, \(As_2O_5\)
