Correct Answer: 4
Solution and Explanation
Acidic oxides react with water to form acids. Among the given oxides:
- Acidic oxides: \(\text{N}_2\text{O}_3\), \(\text{Cl}_2\text{O}_7\), \(\text{SO}_2\), \(\text{NO}_2\)
- Neutral oxides: \(\text{NO}\), \(\text{N}_2\text{O}\), \(\text{CO}\)
- Basic oxides: \(\text{CaO}\), \(\text{Na}_2\text{O}\)
Thus, there are 4 acidic oxides.
Thus, there are 4 acidic oxides.

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
