Decay series
Natural radioactive nuclides are those that occur naturally in the environment, such as uranium-238 or potassium-40, and decay over time through spontaneous processes. In contrast, artificial radioactive nuclides are created in laboratories or nuclear reactors through human processes, like neutron bombardment of stable isotopes, resulting in isotopes like carbon-14 or technetium-99m. While both types of nuclides undergo radioactive decay, their origins and methods of production differentiate them.
artificial radioactivity is carried in synthetically produced radioactive elements used in nuclear reactors and accelerators whereas natural radioactivity is a spontaneous process of disintegration of nucleolus of an atom. This process occurs in elements having atomic number greater than 83

Yes, nobelium is radioactive. It is a synthetic element that does not occur naturally and is produced in laboratory settings. All isotopes of nobelium are radioactive and have short half-lives, making them highly unstable.

No. Some are stable.

Yes. From a technical point of view, all elements have isotopes (nuclides) that are radioactive and therefore have half-lives. But the majority of these are artificial - man made, and do not occur in nature on Earth. Even hydrogen has nuclides of deuterium and tritium, deuterium is stable and natural, and tritium has a half life of 12.33 years. Having said that, there are a number of nuclides that are stable and occur naturally.
Decay Series
All isotopes of all elements with atomic number similar or greater than 84 are radioactive, and don't have stable nuclei.
None - they are all radioactive.
Yes, nobelium is an artificial element and radioactive.
Californium is an artificial radioactive chemical element.
Heavy nuclides are atoms that have a high atomic number and are typically found in the lower region of the periodic table, such as elements like lead, uranium, and thorium. These nuclides often have a high mass and can be unstable, leading to radioactive decay.
