I think you are talking about Lewis dot structures. A dot represents an electron. We pair the dots because only two electrons can share the same orbital. A dash represents a two-electron bond between atoms. Two dashes represent a double bond; three dashes represent a triple bond.

∙ 8y agoIn a chemical formula, a single dot can represent a few different things and you have to have some chemical intuition to figure out what it really means.
I can't do a proper dot here (centered in the line like the upper dot in :, not at the bottom like the lower dot in : or a period), so I will have to use a period.
It might mean "free radical", as in Cl.
It might mean that the compound has an unpaired electron but isn't a free radical. This is pretty rare and is mainly important to electron spin resonance spectroscopists, who use them as "spin labels".
It might mean "associated with but not really chemically bonded to in the ordinary sense", as in CuSO4 . 5 H2O.

How do you draw a Lewis dot diagram for a ligand?
your stupid for looking this up hahaha
Can you draw a Bohr model of nitrogen?
draw a square and put inside of it 7p and 7n. outside draw two circles, in the first circle put two dots (anywhere), the second circle put 5 dots (anywhere) the dots mean electrons and p means protons and n means neutrons.
What does a Lewis dot structure for C2H2F2 look like?
Fluorine has 7 valence electrons each, so they will share one electron. Will look like this, F-F. If your doing a dot structure, just put a pair on the top, side, and bottom of each fluorine atom.
What is the Bohr-Rutherford diagram of the aluminum atom?
two dots on the first shell closest to the nucleus, eight dots on the second shell and then three dots on the outer shell to total 13 two dots on the first shell closest to the nucleus, eight dots on the second shell and then three dots on the outer shell to total 13
What is the Lewis Structure for SeCN-?
.. .. .. :Cl - Se - Cl: .. .. .. There are two dots above the Cl, Se, and other Cl. There are also two dots below the Cl, Se, and other Cl. There are two dots to the left of Cl, and two dots to the right of the other Cl. The dash (-) represents two dots. So, there are a total of 20 electrons. Se has 6, and each chlorine has 7. 6 + 7(2) = 20
My daughter has homework she is stuck on mathematics symbal two dots up at the top with one underneath what does this mean?
The symbol with two dots on the top and one dot below means "because".
What does an a with two dots over it mean?
Do you mean, one dot above two dots? If that's what you intended, it means "therefore." I don't think ever seen two dots above one dot... wikipedia article on this: http://en.wikipedia.org/wiki/Therefore_sign

How do you write the number 10 through 100 in the Mayan system?
10 is two lines 11 is one dot over two lines 12 is two dots over two lines etc... 20 is one dot over a shell. 21 is one dot over one dot 22 is one dot over two dots etc... 39 is one dot over four dots over three lines 40 is two dots over a shell 41 is two dots over one dot 42 is two dots over two dots etc... 60 is three dots over a shell etc... 80 is four dots over a shell etc... 100 is a line over a shell The Mayan number system is a base-20 system. A dot is 1, a line is 5, and up to 19 you can write in one "digit". As soon as the number increases over 20, it goes up into the second "digit" and you stack a dot (this time multiplied by 20) over a shell shape (worth zero). It's just like our number system, except our number system uses a base-10 system.
