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.
Yes, I would put a comma between the date and time. Or, instead of a comma, you can use at, like the first person suggested. Then, if you have at, you do not need a comma. (This depends on the sentence, though--you might need a comma before at.. In most situations, you don't, though, if you're simply putting the date and time alone.) Neon Â· 8 years ago.
