Question
Li has 1 electron in its outer shell, Cl has 7 electrons in its outer shell. Choose the correct option:
Answer: Option B
:
B
Valency of an atom is the number of electrons it is willing to give up oraccept in order to achieve electronic configuration of nearest stable noble gas.
Here, if lithium gives up one electron, it achieves the configuration of helium which is stable. So the valency of lithium is 1.
Similarly, chlorine accepts 1 electron to achieve the configuration of argon. So the valency of chlorine is 1.
