Which of the following elements will form an acidic oxide?
(a) An element with atomic number 7
(b) An element with atomic number 3
(c) An element with atomic number 12
(d) An element with atomic number 19

Solution: The answer is (a) An element with atomic number 7

Explanation: The element with atomic number 7 has electron configuration 2,5, which means it has the ability to gain three electrons and is an electronegative element, and it has atomic number 7. It should be non-metal, as metals will generate acidic oxide when exposed to acid.
