ICSE Class 9 Answered
why does variable valency of an element occur?
Asked by rashmibhattacharjee52 | 08 Apr, 2019, 11:03: PM
Expert Answer
Sometimes, the same element may exhibit one valency in one compound and another valency in other compounds. This property is called as variable valency.
This occurs because of the different arrangement of the electrons in their outermost shell.
