Is Tungsten magnetic? I dropped my boyfriends ring (made of Tungsten) down the place in the doorframe where the door closes, not knowing there was actually a hole there.
Use commas to separate things in a list or series. If you have a series of three or more items, use commas to separate each item. Do not place commas before or after the list or series. Do not use commas when all the items in a series are linked by and, or, or nor.
If you wish, you can add the ending of the ordinal number. The preposition of before the month is usually dropped. You can put a comma before the year, but this is not common anymore in British English. It is common, however, if the date is part of a sentence: The conference takes place 10-12 December, 2003. Example: 5(th) (of) October(,) 2004.
