If you are trying to list 100 words in French, all of which end in "ion", all you have to do is think of 100 words in English that end with the same letters. For the most part, these words have their roots in Latin, and are common across English, French, Spanish, and all the romance languages. And in most cases, especially between French and English, the spelling is the same. Here are some examples:
information
television
collaboration
pollution
complication
eradication
etc.
There are exceptions. Vacation, registration, and others have a different form in French - so be careful to check your dictionary. For those that are the same, the spelling is exactly the same between the two languages, but you will probably have to add accents to the French version of the word.
In compiling your list, I would think up a word, then look it up in the dictionary to see if you need to add an accent or two. But compiling the list should be the easy part.
