Sodium, Magnesium, Aluminium are typical metals. Metallic and non-metallic characters of the elements depend on their atomic size, nuclear charge and ionization potential.

Paper & SolutionSET -1

Solution: Metallic character decreases from left to right along a period of the periodic table because on moving from left to right, size of the atoms decreases and nuclear charge increases. Hence, the tendency to release electrons decreases. Thus, the electropositive character decreases. Marks: 2 Question 11.
