Citations not showing up in text and bibiography

First of all, you have to remove the extension .bib from your \bibliography command; i.e. \bibliography{References} and make sure it is in the same folder as your compiles .tex file, if it is in a sub-directory then use \bibliography{./References/References} as an example.

You also have to make sure the entry is correct in your bibliography .bib file, I can see you use cite{1}, so I presume you have an entry in your .bib file as:

@book{1,
title={Book},
author={Author}
}

... of course you have to fill in all obligatory fields depending on entry type. BibTeX Documentation.

For your compilation to work properly, you should compile in the following manner:

pdflatex file.tex && bibtex file.aux && pdflatex file.tex && pdflatex file.tex

This example being given for a pdflatex output, you could use latex ,xetex or whichever engine you use.

If you get a [?] in your citation instead of a proper reference number, check the log file for something like:

LaTeX Warning: Citation `1' on page 2 undefined on input line 51`
