Question

What are ‘groups’ of the Modern Periodic Table ? What does the ‘group number’ signify.

WhatsApp

Answer

Modern periodic table has 18 vertical columns. Each vertical column accommodates elements with the same outer electronic configuration (i.e., valence electrons), hence have similar properties.

Group number signifies the same outer electronic configuration and similar properties.
