Question

Explain how the periodic table is organized on the basis of electron configuration. Specifically, explain how periods, groups, and blocks are defined by similarities in electron configurations.

Answer 1

it is organized in how electrons are in the outer shell

i.e.

family IA = 1 electron in the outside shell

family IIA = 2 electron in the outside shell

family IIIA = 3electron in the outside shell

family IVA = 4 electron in the outside shell

family VA = 5 electron in the outside shell

family VIA = 6 electron in the outside shell

family VIIA = 7 electron in the outside shell

family VIIA = 8 electron in the outside shell

transition metals are organized in a special place

since their electron configuration has extra areas.

The left side of the table is

"S" left elements

"D" transition elements

"P" right side elements

"F" rarte metalssuch as lanthanide and Actinides

The rows will not change electron configuration in the outer shell, only increase the numebr of electrons in the core of the atm
