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.

Calcium has two valence electrons, so it would have two electron dots in a Lewis electron dot diagram.
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.
The Lewis dot symbol of bromine (Br) is represented by the symbol "Br" surrounded by seven dots, with two dots on three sides and one dot on one side. This configuration shows that bromine has seven valence electrons.
In the electron-dot structure of HBr, hydrogen will have one dot representing its one valence electron, bonded to bromine that has seven dots representing its seven valence electrons. The bond between hydrogen and bromine will consist of two electrons, one from hydrogen and one from bromine, forming a single bond.
H and Li will each have one dot, He and Be will each have two dots, B will have three, C will have four, N will have five, O will have six, F will have seven, and Ne will have eight.
The symbol with two dots on the top and one dot below means "because".
The two dots above a letter, you mean, would be called a diaeresis and/or an umlaut.
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
It is an accent such as FARAAD
It is two dots one on top one on bottom and a line in the middle From:Maddie
what does it mean when you have white dots on your virgina
It means that the "U" now says oo as in boo
fruite, dots taste like fruite, if you mean pacman dots, and if realy you mean dots as in whats on paper, ink, yuek! note: dots realy taste like ink
One or two dots near the outside. They should line up with the dots on the crankshaft.
There is two dots above the Mn, there your two S dots
well the dots mean that there is treasure in that exact are
The total number of dots on two dice - is 42.
