None , is the same as no one, and is properly singular. It is, however, used in both numbers, according as the context seems to make appropriate.

none : Although etymologically equivalent to not (a single) one this word is commonly used as a singular under a mistaken idea that it can not be used correctly as a plural, but many writers of standard English have used it as a plural. The STANDARD DICTIONARY authorizes the use of the word both as a singular and plural according to the meaning of the context. Where the singular or the plural equally expresses the sense, the plural is commonly used and is justified by the highest authority. “Did you buy melons?” “There were none in the market.” “Did you bring me a letter?” “There was none in your box.” “None of the three cases have been received” is correct. In illustrating this point the STANDARD DICTIONARY gives the following quotation: “Mind says one, soul says another, brain or matter says a third, but none of these are right.” And says, “In the preceding quotation the ‘are,' altho ungrammatical, connects ‘right' with any one of the persons named--not with any one of the things named. If is be substituted for ‘are,' ‘right' may be as reasonably connected with ‘mind,' ‘soul,' or ‘brain' as with the persons (or classes of persons) spoken of.” None used with a plural verb is found repeatedly in such English classics as the works of Bacon and Shakespeare, as well as in the Authorized Version of the Bible.
