Answer:
yes its true
Explanation:
Because energy of 3d subshell is greatet than 4s subshell according to n+l rule
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.
