Answer
valency of potassium is 1
Explanation:
number of electrons in K shell is 2
number of electrons in L shell is 8
number of electrons in M shell is 8
number of electrons in N shell is 1
K L M HAVE THERE COMPLETE ELECTRONS IN THEIR SHELL
in N there are 8 electrons but only one electron is there so potassium will give one electron to to any other metal
show the valency of potassium is 1
