Two dots are shown in the electron dot diagram for calcium in group 2 and period 4 with 20 protons and 20 electrons.
A dot and cross diagram of calcium carbonate (CaCO3) involves showing the outer electrons of each element as dots or crosses. Calcium would have two dots in its outer shell (symbolized by "+") and the oxygen atoms each have six dots (symbolized by "-") around them bonding to the calcium atom. The overall diagram would show the arrangement of these dots or crosses to represent the bonding in the molecule.
The Lewis dot diagram for calcium (Ca) has 2 dots on the symbol "Ca" representing its two valence electrons. The Lewis dot diagram for fluorine (F) has 7 dots surrounding the symbol "F," representing its seven valence electrons.
It looks like thisK–Br:except that there are also two dots both above and below the "Br" in the diagram (there are three lone pairs on Br, and none on K)See the Related Questions link about Lewis Dot Structures to the left of this answer for more help with electron dot diagrams!
It depends which element it is. Hydrogen would have one while carbon would have 4 dots. Refer to http://upload.wikimedia.org/wikipedia/commons/thumb/0/02/Electron_dot.svg/300px-Electron_dot.svg.png for additional information.

Calcium has two valence electrons, so it would have two electron dots in a Lewis electron dot diagram.
Chlorine has 7 dots in its electron dot diagram, representing its 7 valence electrons.
There is two dots above the Mn, there your two S dots
it has 4 dots
In the electron dot diagram of Fe2O3, there would be 26 dots shown, representing the total number of valence electrons in the compound. Each dot represents a valence electron from either iron or oxygen.
A dot diagram, or Lewis dot structure, illustrates the valence electrons of an atom. Calcium (Ca) has two valence electrons, represented by two dots, while potassium (K) has one valence electron, represented by a single dot. Therefore, the dot diagram for calcium would show two dots around the symbol, while potassium would show one dot.

The electron dot diagram for calcium (Ca) would show two electrons in the first energy level and eight electrons in the second energy level. The symbol for calcium (Ca) is placed in the center with dots surrounding it representing the valence electrons.
