Are you using a reference management program?
When you are writing your first publication, you may not be aware of how much work it is to format your references to match the style of the journal. Every journal has its own requirements: such as titles in italics, journal names in bold, journal names abbreviated or full, the number of authors listed if more than 5 or 7 or 10… Apart from the right format of the references in the reference list, they also need to have the right format in the text, which usually comes down to the name of the first author and the year of publication, or simply a number. In addition, you need to keep track of the references in the text and make sure they show up in the right order in your reference list. Using a reference management program will save you lots of time and frustration.
