oxygen atoms
Okay, so I need some help answering this. [& if you can tell me how to do it, too, that'd be great]
How many oxygen atoms would it take to form a line one centimeter long? [if they were placed side-by-side]
Thanks to anyone who helps. :]]]
I really dont get how to do it.

Roughly 71,428,571 atoms. One oxygen atom is about 0.14 nanometers is diameter. There are 10000000nm in a cm. 10000000/0.14=71428571.4. Round down to your answer.
0.140nm-0.152nm is the Van der Waals radius of an oxygen atom. It's the distance between electrons on opposite sides of a typical oxygen shell.

This is a challenging question to answer. Try using avagadro's number to calculate the atomic weight of the oxygen atom...then see if you can figure out how many oxygen atoms are in a cubic centimeter, then you will probably have to work your way backwards. Also, you could try looking up quantum physics...this can be helpful. Good Luck.
