Question

 The subshell electronic configuration of K(Z=19)​

Answer 1

Answer:

hello friend here ur answer

Answer 2

Answer:

Potassium, atomic #= 19 , therefore there are 19 electrons. The electron configuration would be - 1s2 2s2 2p6 3s2 3p6 4s1. Then adding exponents- 2+2+6+2+6+1=19 which is the atomic number and therefore the number of electrons.
