Question

What is the charge on a sulfur atom that contains 18e−e−?

Answer 1

Sulphur atom has 16 as its atomic number, which is also the same number of protons and the same number of electrons:

Z = 16

P = 16

e- = 16

But when we have a Sulphur ion, it is usually -2, and since we have 18 electrons in this case, the charge will be -2
