Non-metals can form acidic oxides in general. Non-metal have 4 to 8 electron in the outermost shell. The electronic configuration of given element are (a) i.e., 7 = 2,5 (b) i.e., 3 = 2,1 (c) i.e., 12 = 2,8,2 (d) i.e., 19 = 2,8,8,1
So, an element with atomic number 7 (electronic configuration 2,5) is non-metal (N) and it will form an acidic oxide. Rest three elements atomic numbers, 3(Li),12 (Mg), and 19 (K) are metals and hence form basic oxides.

Which of the following elements will form an acidic oxide ?a)An elemen...
An acidic oxide is an oxide that reacts with water to form an acid. It is important to note that the acidity of an oxide depends on the element it is derived from. In this case, we are given four elements with different atomic numbers and we need to determine which one will form an acidic oxide.
a) An element with atomic number 7:
- The element with atomic number 7 is nitrogen (N).
- Nitrogen forms an acidic oxide called nitrogen dioxide (NO2).
- When nitrogen dioxide reacts with water, it forms nitric acid (HNO3), which is a strong acid.
- Therefore, option 'A' is the correct answer.
b) An element with atomic number 3:
- The element with atomic number 3 is lithium (Li).
- Lithium does not form an acidic oxide. It forms lithium oxide (Li2O), which is a basic oxide.
- Therefore, option 'B' is not the correct answer.
c) An element with atomic number 12:
- The element with atomic number 12 is magnesium (Mg).
- Magnesium does not form an acidic oxide. It forms magnesium oxide (MgO), which is a basic oxide.
- Therefore, option 'C' is not the correct answer.
d) An element with atomic number 19:
- The element with atomic number 19 is potassium (K).
- Potassium does not form an acidic oxide. It forms potassium oxide (K2O), which is a basic oxide.
- Therefore, option 'D' is not the correct answer.
In summary, the element with atomic number 7 (nitrogen) will form an acidic oxide, while the other elements mentioned (lithium, magnesium, and potassium) will form basic oxides.
