Question

write all the laws/principles which are followed for writing the electronic configuration of the atoms​

Answer 1

Answer:

AUFBAU PRINCIPLE

HUND's RULE

PAUL's EXCLUSION PRINCIPLE

Explanation:

1   List the electrons by the similar energy groupings (subshells). The notation is:

• Layer Number
• Subshell Name
• Count in that Subshell

2  Use the basic order - called aufbau

3  Place them in order of filling with commas between.

4  Remember aufbau exceptions. Mostly in the transition metals. You get 3s2 often as 3s1.

5  Maybe, my work to resolve those exceptions will become peer-reviewed, but until then the above is the procedure.

if it is helpful means just leave a thanks..........
