how will u find the valency of chlorine, potassium and sulphur
Answers
Answer:
Valency of chlorine: The electronic configuration of chlorine = 2, 8, 7.
Since, chlorine has 7 (more than 4) electrons in its outermost shell.
Potassium can donate one electron and then it will become 8 electrons in the outermost shell. If potassium donates one electron and becomes potassium ion, the configuration will be 2, 8, 8. ...
Therefore, the valency of potassium is 1.
Valency of Sulphur: The electronic configuration of Sulphur = 2, 8,6.

Answer:
Valency of chlorine: The electronic configuration of chlorine=2, 8, 7.
Since, chlorine has 7 (more than 4) electrons in its outermost shell.
Therefore, valency of chlorine = 8-number of electrons in outermost shell
=8−7=8−7
=1=1
Valency of Sulphur: The electronic configuration of Sulphur=2, 8,6.
Since, Sulphur has 6 (more than 4) electrons in its outermost shell.
Therefore, valency of chlorine = 8-number of electrons in outermost shell
=8−6=8−6
=2=2.
valency of pottasium= 1
