Sodium does occur naturally on Earth. It is a common element found in various minerals, soils, and water bodies. Sodium is also a key component of salt, which is abundant in the Earth's crust and oceans.
In ionic bonding between sodium and fluoride in sodium fluoride, one electron transfers from sodium to fluoride. Sodium loses an electron to achieve a stable octet configuration, becoming a positively charged ion (Na+), while fluoride gains an electron to achieve a stable octet, becoming a negatively charged ion (F-). The electrostatic attraction between the oppositely charged ions results in the formation of an ionic bond.
Sodium hydroxide is not found naturally in its pure form, as it is a man-made chemical compound. It is typically produced through the chemical reaction of sodium carbonate with calcium hydroxide.
Sodium is a highly reactive element that easily forms compounds with other elements, such as chlorine in the form of sodium chloride (table salt). This tendency to react with other substances means that pure sodium is not typically found in nature. Instead, sodium is usually found in compounds in minerals or in seawater.
Sodium is an atom. It is a chemical element with the symbol Na and atomic number 11. Sodium exists as single atoms and does not naturally occur as a molecule in its elemental form.
It is manufactured.
"Synthetic" could be another word for something that does not occur naturally.

Calcium fluoride does not actually occur naturally in the human body and as such doesn't really contain a function. Outside of the body it is used in the production of materials.
Pure water does not contain fluoride, but much drinking water does contain fluoride that is deliberately added to reduce tooth decay of children who drink the water. Some drinking water supplies also contain fluoride naturally.

The isotopes are not manufactured for specific uses, they occur in nature naturally.
Sodium hydroxide is not found naturally in its pure form, as it is a man-made chemical compound. It is typically produced through the chemical reaction of sodium carbonate with calcium hydroxide.
All existing products which do not occur naturally are manufactured. This includes items as diverse as computers, phones, toys, clothing, cars, musical instruments, and everything else which does not occur in nature.
Because sodium reacts with air (and even more vigorously with water), it does not exist in elemental form on Earth. Its most common form is in salt (sodium chloride), from which it can be extracted by the electrolysis of molten salt.
