The Scientists Dilemma!

Chemistry Level 1

There are two Scientists whose proposed their respective periodic tables based on Aufbau Principle

  • Scientist 1 proposed his periodic table by following Aufbau principle.

  • Scientist 2 proposed his periodic table by not following Aufbau principle.

True or False ?

\(\text{Potassium} (K - 19)\) is placed in \(s-block\) of Scientist 1 periodic table whereas it is placed in \(d-block\) in Scientist 2 periodic table.

  • When one is not following Aufbau principle the electrons get filled in the order : \[1s,2s,2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, etc\]
