Question

Define valency by taking example of silion and oxygen.​

Answer 1

Answer:

Silion:-It has two electrons in its first shell, eight electrons in the second shell, and four electrons in the third shell. Since the electrons in the third shell are the outermost electrons, silicon has four valence electrons.

Oxygen has a valence of two, and it has six valence electrons. It can form single or double bonds. Nitrogen has five valence electrons, five electrons in its outer shell, and needs three electrons to complete that outer shell
