How to calculate valency of d block from we electronic configuration
Asked by archanakad | 25th Aug, 2020, 08:59: PM
The number of valence electrons in d-block elements is most often equal to their group number which is equal to the number of electrons in the "valence shell."
for example, scandium metal's electrons per shell are 2,8,9,2 and its outer shell has only 2 electrons, so the valence electron count of scandium is 2.

- How we get valency 2 in sulphur?
- How can I draw electronic configuration of calcium in a shell
- why element Helium and Argon are chemically inactive?
- Electron dot structure
- Write electonic configuration of first 50 elements.
- How can i know the valency of a compond to react it with another elemet to form a chemical reaction? For example - Suppose I have to make . Then i have to first react Carbon with Oxygen then react that compond with calcium. So how will i know the valency of compound formed from reaction of carbon with oxygen. We can know the valency of elements from their atomic number and electronic configuration, but how can i know the valency of compound? Please help,waiting for your reply, Thank you.
- sir please explain how we find valence of elements
