Answer 2

Explanation :

In potassium, the 19th electron enters into 4s subshell instead of 3d subshell in accordance with the Afbau Principle.

In potassium, the 19th electron enters into 4s subshell instead of 3d subshell in accordance with the Afbau Principle.- The energy of 4s subshell is lower than the 3d subshell.

In potassium, the 19th electron enters into 4s subshell instead of 3d subshell in accordance with the Afbau Principle.- The energy of 4s subshell is lower than the 3d subshell.- According to the Afbau principle, the subshell with lower energy must be filled first.

In potassium, the 19th electron enters into 4s subshell instead of 3d subshell in accordance with the Afbau Principle.- The energy of 4s subshell is lower than the 3d subshell.- According to the Afbau principle, the subshell with lower energy must be filled first.- Hence, the 19th electron of potassium enters into 4s subshell instead of 3d subshell.
