Answer:
Sulphur is the element having atomic number 16. Its valency is 6 and forms anion.
Step-by-step explanation:
Sulphur is the element having atomic number 16 and mass number 32 which means sulphur has 16 proton, 16 electron and 16 neutron. 2 electrons are present in the first shell, 8 electrons are present in the second shell and 6 electrons are present in the outermost shell. Sulphur requires 2 electrons to become stable so that's why sulphur take 2 electrons and become anion. its valency is 6 which means 6 electrons are present in the outermost shell of sulphur atom.
