What is the difference between valence shell electrons and valency ?

Open in App
Solution

The combining capacity of an atom is called its valency. Actually it can be defined as the number of electrons that an atom may lose (or) gain during a chemical reaction (or) the number of electrons shared. Ex: In water molecule H₂O (H - O – H) Valency of Hydrogen is ‘ 1 ‘ (as it combines with Oxygen atom by one single bond) and valence electrons in Hydrogen = 1 Valency of Oxygen is ‘2’ (as it combines with two Hydrogen atoms by two bonds).but valence electrons in oxygen = 6 . ​​​The number of electrons in outermost shell (or) valency shell of an atom are called valence electrons.
