Sulfur can form the sulfide ion (S2-) and the disulfide ion (S22-) on its own. When combined with oxygen it can form the sulfate ion (SO42-) and sulfite ion (SO32-).

Is electricity a negative charge?
A negative electrical charge occurs when you have more electrons than protons (electrons are negatively charged, and if you have more -'s than +'s the overall charge will be negative).

What are rules in forming the possessive of singular or plural noun?
Singular possessives are formed by adding an apostrophe s to the end of a noun.Plural nouns that end in -s, possessives are formed by adding an apostrophe after the existing -s; for irregular plural nouns that don't end with -s, the possessive is formed by adding the apostrophe s the same as a singular noun.ORThere are two accepted forms for possessive singular nouns ending in s:Add an apostrophe (') after the existing s at the end of the word; for example, "Put it on the boss' desk."Add an apostrophe s ('s) after the existing s at the end of the word; for example, "Put it on the boss's desk."The -s's is the most commonly used, but if you are a student, use the form that is preferred by your teacher.
