How will you find the valency of chlorine, sulphur and magnesium?
Chlorine:
Atomic number \(=\)
Number of protons \(=\) \(=\) Number of electrons
Electronic configuration or electron distribution \(=\)
Chlorine to complete its outermost shell. Hence, its valency is .
Sulphur:
Atomic number \(=\)
Number of protons \(=\) \(=\) Number of electrons
Electronic configuration or electron distribution \(=\)
Sulphur to complete its outermost shell. Hence, its valency is .
Magnesium:
Atomic number \(=\)
Number of protons \(=\) \(=\) Number of electrons
Electronic configuration or electron distribution \(=\)
Magnesium to complete its outermost shell. Hence, its valency is .
