Define valency by taking examples of silicon and oxygen?
The valency of an element is the combining capacity of that element. The valency of an element is determined by the number of valence electrons present in the atom of that element.If the number of valence electrons of the atom of an element is less than or equal to four, then the valency of that element is equal to the number of valence electrons. For example, the atom of silicon has four valence electrons and so, it has valency equal to four.On the other hand, if the number of the number of valence electrons of the atom of an element is greater than 4, then the valency of that element is obtained by subtracting the number of valence electrons from 8. For example, the atom of oxygen has 6 valence electrons. and so, the valency of oxygen is (8 – 6) 2.
Define valency by taking examples of silicon and oxygen?
Valency:- The minimum no.of electron which is gain, loss or shared by any elements to complete it's octate or duplate....eg:- Oxygen:- It will gain 2electron to complete it's octate.... Silicon :- It will share 4 electrons to complete it's octate....
