Question

7. Deline valency by taking examples of silicon and oxygen.​

Answer 1

Answer:

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. Thus, the valency of silicon is four. ... Thus, the valency of oxygen is (8 ˆ' 6) i.e., two
