Question

What are the periodic trends in the modern periodic table?

Answer 1

The major periodic trends in the modern periodic table are electronegativity, electron affinity, ionization energy, atomic radius, melting point, and metallic character.

Electronegativity- It increases from left to right across a period and decreases from top to bottom down a group.

Ionization Energy- It increases from left to right across a period and decreases from top to bottom down a group.

Electron Affinity- It follows the same trend as that of electronegativity.

Atomic radius- It decreases from left to right across a period and increases from top to bottom within a group.
