Which of the following is the most basic oxide ?
Updated On: Oct 13, 2023
- Al2O3
- Sb2O3
- Bi2O3
- SeO2
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Basic oxides are oxides that react with water to form a base (alkaline solution) when dissolved. Bismuth (III) oxide (Bi2O3) is a basic oxide that reacts with water to form a basic solution.
So, the correct option is (C): Bi2O3

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
