If you are looking at a nitrogen atom by itself it will have 5 electrons (dots) surrounding it. The number of dots corresponds to an atom's location on the Periodic Table.
Starting from left to right (excluding transition metals) you increase 1 electron per column. So, looking at the 3rd row, sodium (Na) will have 1 dot, magnesium 2, aluminum 3, silicon 4, etc.
There are 4 electrons represented in an atom of carbon.

4.
The number of valence electrons in the atom.
The electron-dot representation of a carbon atom show only four dots because the dots represent only the valence electrons (the ones placed in the outermost shell). The carbon atom has four electrons in it's outermost shell. !
the dots are the number of electrons in an elements valance shell (last shell). if it has no dots, it means it has lended its electrons to another element to become stable like its nearest noble gas.
The electron-dot structure for HBr would be:H:Br: (with two more pairs of dots on the top and bottom of Br)
The dot structure for I will have have 7 dots around it. This will consist of 3 lone pairs, and then 1 single electron.

5 dots around AS.

The dot structure for CH2I2 starts with the carbon atom in the center. To the right and left are a singly bonded H atom. Above and below are a singly bonded I atom, each of which has a pair of dots on each unbonded side.
The dot structure for I will have have 7 dots around it. This will consist of 3 lone pairs, and then 1 single electron.
Valence electrons.
Since it is a tetrabromide, there will be four dots around the atom.
how do you draw an electron dot diagram for silicon
However many valence electrons there are, which I believe is 3
