www.elmhurst.edu/~ksagarin/chem101/tutorials.html - 6k - this is a website with bohr diagrams.

  You put the # of protons and neutrons in the middle of a circle and then you draw more circles around the central cirlce. Each new ring has a specific # of electons that goes on that orbital.
1st ring: 2 electons
2nd ring: 8 electons
3rd ring: 8 electons
4th ring: 18 electons
5th ring: 18 electons
6th & 7th rings: 32 electons

that's how you make a Bohr diagram:)

you would draw a nucleus and put your number of protons in it and your number of neutrons and then you would put your electrons inthe circles you will draw and there can be :
2 in the first shell
8 in the second shell
18 in the third shell
32 in the fourth shell
and then how ever many were left after taking the numbers of elecrons and subtracting the shell numbers and in the fifth shell put how ever many are left after subtracting

does anyone know a web site that shows all the bohr diagrams for all the elements rather than a worksheet for them

A bohr model is just circles around a small circle to show the number of protons and electrons the element has. You draw a small circle and put the number of protons and electrons in the middle, and then you draw the circles around it to represent each energy level the element has. When you finish drawing the circles around it, you label the number of valence electrons are in each energy level. I think that is how it goes. That is how i do mine in school.
