Answer:

1s2 2s2 2p6 3s2 3p6 4s1

Explanation:

The reaction of potassium and sodium metals with water is fast and highly exothermic. So much heat is released that the metals catch fire spontaneously when added to water.

Hence, it is common to see in textbooks that sodium and potassium reacts violently with water.

When added to water, potassium burns with a purple flame.
