The document discusses the determination of valency for various ions and specifies the valency where necessary. It lists several ions along with their corresponding valency, such as cobalt(II) for Co, and copper(I) for Cu, while indicating that certain ions do not require a valency designation based on their block classification. Additionally, it categorizes these ions into d block, s block, and p block elements.

What determines what needs the valency- Give the name of the following.docx
- 1. What determines what needs the valency? Give the name of the following ions. Include the valency where needed. For example, leadV) a. Co2+ Cobalt ion b. Be2+ Beryllium(ll) c. Cu Copper(l) d. N Nitride ionx ion 3- ion Pa a. cobalt(II) ion b. beryllium ion c. copper(I) ion d. nitride ion Solution d block elements needs to be specified valency a) Co is d block element So, we need to mention valency Answer: Cobalt(II) b) Be is s block element So, we don’t need to mention valency Answer: Beryllium c) Cu is d block element So, we need to mention valency Answer: Copper(I) d)
- 2. N is p block element So, we don’t need to mention valency Answer: Nitride
