Yes NaCl --> Na+ + Cl- Cl- + Cl- --> Cl2 hail you stupidity.
No, it is the most common dissolved ion in the ocean. The most common element by mass is oxygen as the ocean is still mostly water.
The most common element dissolved in seawater is chlorine, primarily in the form of chloride ions (Cl⁻). Chloride ions account for about 55% of the total dissolved salts in seawater. Sodium, in the form of sodium ions (Na⁺), is the second most abundant, and together, these two elements contribute to the salinity of ocean water.

Oxygen, hydrogen, sodium, and chlorine.
The most important dissolved elements in ocean water are sodium and chlorine, which together make up the majority of the salt content (salinity) of seawater. Other important dissolved elements include magnesium, calcium, and potassium. These elements are essential for marine life and play a key role in ocean chemistry.

The total amount of dissolved salts in ocean water is referred to as "Salinity". :)
Oceans are predominately water, which is hydrogen and oxygen, but they also have a considerable amount of salt in them. That's sodium and chlorine ions. Dissolved oxygen is present, or fish and a lot of other animals would die. Carbon dioxide (CO2, which is carbon and oxygen) as well as a number of other gases are also present. Just about any element that can become soluble (including gold) and is washed downstream from rivers can be found in sea water.
