Concept explainers
Interpretation:
The difference between Lewis symbol and Lewis structure is to be determined.
Concept introduction:
The electrons that are present in the outermost (valence) shell of an atom are termed as valence electrons.
A Lewis symbol represents the
A Lewis structure representsconnectivity of atoms within the molecule.
Rules of writing Lewis symbol:
Dots are placed above and below as well as to the left and right of symbol.
Number of dots is important in Lewis dot symbol but not the order in which the dots are placed around the symbol.
In writing, symbol pairing is not done until absolutely necessary.
For metals, the number of dots represents the number of electrons that are lost when the atom forms a cation.
For second period non metals, the number of unpaired dots is the number of bonds the atom can form.
Atomic ions can also be represented by dot symbols, by simply adding (for anions) and subtracting (for cations) the appropriate number of dots from Lewis dot symbol.
The octet rule states that every atom reacts to form bonds till its octet of electrons gets completely filled.
