Iodine in its natural form is I2, two iodine atoms bonded with a single covalent bond. There are 6 non-bonded valance electrons on each atom, so there are 12 electrons in the electron-dot structure.
Iodine is a halogen, and as such, it has 7 valence electrons. These will appear as dots around the "I" symbol, in three pairs and one single.
Bonds are formed by the Sharing of electrons. If you wanted a negative bond, then you'd share negative electrons. For example... Hydrogen and Fluorine Hydrogen has one electron shown by it's configuration. 1s1 Notice that hydrogen's sole electron is also it's valence electron and located in the first energy level. Florine has seven electrons shown by it's configuration 1s22s22p5. it's all in the electron sharing.
None. There will be two pairs (for a total of 4 electrons) on the Oxygen atom in the water molecule.
The outer-most electrons are the only ones included in the orbital filling diagram and the electron dot diagram because the outer-most electrons are the only ones that need to be used in chemical reactions and bonding, so the other electrons are insignificant in these diagrams.
That is chlorine and it has seven valance electrons.
Yes, in a Lewis diagram, the valence electrons are shown by dots around them.

they are the electrons in the outer shell of the atom(valence electrons)
As far as measurements have shown an electrons is almost a perfect sphere.

Electrons shown in an electron dot diagram are the valence electrons. As a "for instance" here, look at hydrogen and lithium. Each one has a single electron in their outer most or valence shell, and so each will be shown by writing the chemical symbol and by adding a single dot. H. Li.
Two dots are shown in the electron dot diagram for calcium in group 2 and period 4 with 20 protons and 20 electrons.

In a Lewis dot structure (also called an electron dot structure) there are no inner electrons and shells shown because Lewis dot structures are usually used to show bonds between elements, and the inner electrons are never usually involved with the bonding of atoms.
