Table Of Contents
Which anion has valency 2?
An anion is a negatively charged ion. The valency of an anion is the number of electrons it has in its outermost orbital. The valency of an anion can be 2, 3, or 4.
Is sulphate an anion with valency 2?
In order to answer this question, we must first understand what valency is. Valency is defined as the number of electrons in the outermost orbital of an atom. The element sulphur has six electrons in its outermost orbital, so its valency is 2.
Which element is a metal with valency of 2?
Zinc (Zn) is a metal with valency of 2.
Which element is a nonmetal with valency 2?
The answer is boron! This element is a nonmetal with valency 2, which means that it can form two chemical bonds with other atoms.
