Statement (A) : The elements like H, Li try to get two electrons in their outermost shell. Statement (B) : The elements like Na, Cl try to get eight electrons in their outermost shell. Statement (C) : According to Lewis theory the number of dots around the symbol represents the

A
All the statements A,B and C are correct
B
All the statements A,B and C are incorrect
C
A,B are correct and C is incorrect
D
A, B are incorrect and C is correct

Solution:

Hydrogen atom gains one electrons and Li atom lose one electron to get He electronic configuration to attains stable.

Na atom lose one electron to get Ne configuration ${(Na}^{+})$ and Cl atom gains one electron to get Organ configuration ${(Cl}^{-})$ both are having 8 electron in their outermost shell.

Valence electrons are represented by Lewis dots.
