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.

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.
How many electron dots does calcium have?
Calcium has two valence electrons, so it would have two electron dots in a Lewis electron dot diagram.
What is the Lewis dot symbol of bromine?
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.
Draw the electron-dot structure for HBr?
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.
How does the Lewis dot structure of zinc look like?
zncl2 is linear. so, put the chemical symbols zn, cl and another cl (where zn is between two Cl symbols in a straight line) and put two dots in two spaces between zinc and chlorine molecules. (so u'll have four electrons (dots) surrounding zinc). this is the lewis structure and its that simple becoz there are no lone pairs on zinc as its valency is two.
