It's hard to do Lewis formulas with a word processor...
But calcium carbonate is an ionic compound, the Ca has given up its two outer shell electrons and has a 2+ charge. The carbonate has a central carbon with the 3 oxygen molecules around, evenly spaced. One of the O's has a double bond with the C, the other have a single bond and 3 paired electron orbitals, each having a negative charge, so in the end the C and each O is surrounded by 8 electrons:
-O:
Ca2+ C::O
-O:
Connect the floating oxygen ions to the carbon and finish the electron pairs around the oxygens.
Calcium phosphate is the chemical name for the molecular compound of the formula Ca3(PO4)2. The Lewis dot structure representing calcium phosphate is:
No, not exactly. It is an ionic compound so it would not have a Lewis dot structure. However, the carbonate anion, CO3^2- does have a Lewis dot structure.

Lewis dot formula
The difference between the Lewis dot structure and the structural formula is that the formula only shows the bonds that have formed whereas the dot structure shows all the valence electrons, including lone pairs, in that molecule.

Sulphur difluoride is the chemical name for the molecular formula SF2. SF2 can be represented by the Lewis dot structure of: .. .. ..:F : S: F: .. .. ..
Lewis structures are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. They are also called Lewis dot diagrams, electron dot diagrams, and electron dot structures. See the link below for Lewis structure.
The Lewis dot formula for bromine chloride is very easy to write. It starts with a singly bonded Br and Cl atom in the center. On every unbonded side of both atoms there is a single pair of dots.
