What is the full electron configuration for potassium?
Understand the Problem
The question is asking for the full electron configuration of potassium (K), which is an element in the periodic table. To express this, we will list the arrangement of electrons in the atomic orbitals.
Answer
1s2 2s2 2p6 3s2 3p6 4s1
The full electron configuration for potassium is 1s2 2s2 2p6 3s2 3p6 4s1.
Answer for screen readers
The full electron configuration for potassium is 1s2 2s2 2p6 3s2 3p6 4s1.
More Information
Potassium has 19 electrons, distributed among the energy levels, ending with a single electron in the 4s orbital.
Tips
A common mistake is to overlook the final electron in the 4s subshell or to misplace it in a 3d orbital, which is incorrect for potassium.
