periodic table. Why?
​

Answer 1

Explanation:

Modern periodic law: The Modern periodic law states “The chemical and physical properties of elements are a periodic function of their atomic numbers”.

Metallic character increases down each Group of the Table as the outer electrons are further from the nucleus and require less energy for their removal. (a) metallic character decreases from left to right in each Period.

Answer 2

Answer:

In modern periodic table the metallic property of elements increaincrin.priodic table because as tendency to lose electron also increases .electropositive nature also increases .so,metallic nature increases from bottom of the group .

From going left to right metallic character decrease as ionization energy increases .
