Some common places you may find scientific articles online include:
On Pubmed, the journal name is listed, typically abbreviated, at the top left of the page above the title. If you don't understand the abbreviation, google it to find the full name.
On Science Direct, the journal name is featured prominently above the title.
On Springer Link, the journal name is just below the authors' names.
On Wiley, the journal name is featured prominently above the title.
Articles may also be hosted on a website owned directly by the journal itself. In this case, the journal name will typically be prominent somewhere on the page. If you cannot see it, the name will also typically be in the address bar.
If the journal isn't on one of these website options, the journal name should still be near the top.
