Question

electronic configuration of potassium​

Answer 1

Answer

Potassium is a chemical element with the symbol K and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.  

Symbol: K

Atomic mass: 39.0983 u

Atomic number: 19

Electron configuration: [Ar] 4s¹

Van der Waals radius: 280 pm

Melting point: 63.5 °C

Boiling point: 758.8 °C

Answer 2

Answer:

Therefore the Potassium electron configuration will be 1s22s22p63s23p64s1. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.
