What is the Octet Rule? - BYJU'S
The chlorine atom holds 7 electrons in its valence shell and can attain an octet configuration by gaining an electron. The outermost shell of sodium has one electron. If it loses this electron, the second shell …
Electronic Configuration Of Iron - BYJU'S
Does iron have a full valence shell? According to the electron configuration, the last shell of iron has two electrons, while the d-orbital has a total of six electrons. As a result, iron has eight valence electrons.
Define Valency - BYJU'S
What is the importance of Valency? The importance of valence: when two atoms react, their outer shell first comes into contact and it is, therefore, the outer shell electron that is normally involved in a …
What Is VSEPR Theory? - BYJU'S
The Valence Shell Electron Pair Repulsion Theory, abbreviated as VSEPR theory, is based on the premise that there is a repulsion between the pairs of valence electrons in all atoms, and the atoms …
