Dear florine is natural non metal element, it is very reactive ,so it not exist as free element , it is the first member of halogen group in Periodic Table. it has special chemical and physical properties , the most is poisinous.
No, carbon is not considered a type of synthetic element. It is considered a type of natural element since it occurs on Earth naturally.

* 238 is the atomic mass of a natural uranium isotope. * 14 is the atomic mass of a carbon isotope.
Carbon 12 is the most important non-radioactive isotope of carbon - 98,93 %; the other is carbon 13 with 1,07 %. Carbon 14 is also a natural isotope but radioactive; it is important for radiocarbon dating of materials from organic origin.

Ozone is a tri oxygen molecule. It is formed in a natural process by the action of UV light on oxygen molecule.
The number of nucleons (protons and neutrons). Since both protons and neutrons are pretty close to one atomic mass unit, it's also approximately the mass of the atom.

Natural carbon-14 is formed in the upper atmosphere when cosmic rays collide with nitrogen atoms, producing carbon-14 isotopes. This radioactive isotope then mixes with carbon dioxide in the atmosphere and is taken up by living organisms through photosynthesis, becoming part of their tissue.
14 carbon is radiative, natural form of Carbon Formed by cosmic ray interactions of N2 in the atmosphere.

It doesn't. Under natural conditions, carbon 14 generally forms from nitrogen 14. A high energy neutron from space strikes the nitrogen nucleus, causing it to eject a proton, ultimately forming a carbon 14 atom and hydrogen 1 atom. It can also occur via neutron capture by carbon 13. Currently there is an overabundance of carbon 14 in the atmosphere as a result of nuclear testing.
Carbon 12 has 6 protons and 6 neutrons. Carbon 14 has 6 protons and 8 neutrons. Carbon 12 is abundant in the environment, accounting for 98.89% of all carbon and is a stable isotope of carbon. Carbon 14 accounts for only about 1 trillionth of all of the carbon on Earth and is radioactive, with a half life of roughly 5700 years, which makes it good for use in dating fossils etc

natural gas contains carbon
Carbon-12 (98.93%), Carbon-13 (1.07%), and Carbon-14 (1 PPT) all occur naturally. However, Carbon-14 is radioactive (halflife 5,730±40 years) and is being produced only high in the atmosphere by bombardment of nitrogen gas by cosmic rays.
Carbon 13 is stable; it does not decay into carbon 14. Since carbon 14 has a greater mass, such a decay would be impossible.
