Generating the Lewis Dot Diagram for a main group element involves the following steps: -
Answer✔✔-a.) Determine the Group Number of the element in question. This is the number at
the top of the column in which the element is located on the PTOTE (Figure 1.1).
b.) The Group Number indicates the number of valence electrons possessed by the atom in the
valence shell.
c.) Write the atomic symbol for the element and imagine it is contained in a four-sided box.
d.) Place dots (representing electrons) around the symbol. Use only the four sides of the box.
e.) Place electrons singly at first, one per side.
f.) Once each side has a single electron, continue by pairing electrons until the total number of
electrons is placed (equal to the Group Number).
When complete, the LDD can be used to determine two important items: - Answer✔✔-1.) The
number of UNPAIRED electrons - this is the number of bonds the atom will form. By making a
bond, the atom will gain an electron for its valence shell (one for each bond made).
