Radioactive elements are unstable and will decay into other elements in a decay chain.
Non-radioactive elements are stable and won't commence into radioactive decay.
Radioactive elements can be found from atomic number 84 onwards.
Radioactive materials contain unstable atoms that decay and emit radiation, while non-radioactive materials do not emit radiation. Radioactive materials can be harmful to living organisms due to their ionizing radiation, whereas non-radioactive materials are generally considered safe for everyday use.
This is called a concentration gradient. It represents the difference in the concentrations of a substance between two regions, with molecules naturally moving from high to low concentration areas to reach equilibrium.
In chemistry, a normal solution is based on the equivalent weight of a substance, while a molar solution is based on the molarity of a substance. The main difference is in how the concentration of the solution is measured and expressed.
A pure substance has a specific density that remains constant regardless of the amount of substance present. An impure substance may have a density that varies depending on the amount and type of impurities present in the substance.
The main difference between carbon-12 (6C12) and carbon-14 (6C14) is the number of neutrons they have in their nuclei. Carbon-12 has 6 neutrons, while carbon-14 has 8 neutrons. This difference in neutron number affects the stability and radioactive properties of the two isotopes.
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.
Radioactive minerals are unstable and emit radiation at a constant rate. They also have half lives and lose energy overtime. Nonradioactive minerals are stable, and by there own are incapable of emitting energy.
There is no difference

The difference between the freezing and boiling points vary from substance to substance.
Radioactive materials contain unstable atoms that decay and emit radiation, while non-radioactive materials do not emit radiation. Radioactive materials can be harmful to living organisms due to their ionizing radiation, whereas non-radioactive materials are generally considered safe for everyday use.
The average time needed for half of the nuclei in a sample of a radioactive substance to undergo radioactive decay is called the "half-life." This period is a characteristic property of each radioactive isotope and varies significantly between different substances. During one half-life, the quantity of the radioactive material reduces to half of its original amount.
Chemists prefer the expression pure substance.
The difference between a homogeneous mixture and a pure substance is that a pure substance has a fixed composition and cannot be separated because it is chemically bonded and a homogeneous mixture can be separated.
i think it is homeostasis
No.
are radioactive and the actinides are not
