Sorry about the wierd spacing but there is a single bond on the top of the N and on the bottom
It represents the number of valence electrons in the atom.
G.N. Lewis
There is no element symbolized as "M". If you find M in a chemical formula or equation, it most likely means any metal element (i.e., iron, silver, etc). There are three metals which begin with M: magnesium (Mg), manganese (Mn) and molybdenum (Mo).
They can also be called Lewis Dot Structures or Diagrams, named after a scientist names Gilbert Norton Lewis
to find the electron dot configuration of an element simply draw dots, symbolizing valance electrons, in a way that they are farthest from each other around the symbol of the element you are using.
Formula: NI3
The molecular formula for nitrogen iodide is NI3.
P..h.p
The chemical formula of nitrogen triiodide is NI3.
linear formula
The formula for nickel(II) arsenate is Ni3(AsO4)2.
The electron dot formula, or Lewis dot structure, for potassium (K) shows one dot representing its single valence electron, since it is in Group 1 of the periodic table. For chlorine (Cl), the electron dot formula displays seven dots around the symbol, representing its seven valence electrons in Group 17. When potassium and chlorine react, potassium donates its one electron to chlorine, resulting in the formation of K⁺ and Cl⁻ ions.
Lewis dot structure
The formula of cyclopentane is C5H10. The electron dot structure of cyclopentane would show each carbon atom with four valence electrons forming single bonds with adjacent carbon atoms, resulting in a pentagon shape.
The electron-dot formula for HCl shows that hydrogen has 1 valence electron denoted as ● and chlorine has 7 valence electrons denoted as ●●●●●●●. The bond between hydrogen and chlorine is represented by a single line, indicating a single covalent bond.
The chemical formula for 1 atom of nitrogen and 3 atoms of iodine is NI3.
