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.

What is the difference between radioactive and non radioactive materials?

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.


What is the difference in concentrations of a substance between two areas called?

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.


What is the difference between a normal solution and a molar solution in chemistry?

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.


Difference between pure and impure substance from density?

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.


What is the two difference between 6C12 and 6C14?

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.

What is the difference between a non-radioactive substance and a radioactive substance?

Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.


What is the difference between radioactive and non-radioactive isotope?

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.

What is the name of the average time needed for half The nuclei and a sample of radioactive substance to undergo radioactive DS our B radioactive substance to undergo radioactive decay?

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.
