What elements are radioactive in their most common form?
anything past bismuth and 2 elements in middle (promethium and another I don't remember). some researchers believe bismuth is also naturally radioactive, but with a half-life longer than the age of the universe.
Is neon radioactive?
No radioactive isotopes of neon are ordinarily found in nature. All elements have radioactive synthetic isotopes, however.
What element reacts with bismuth?
Bismuth typically reacts with oxygen to form bismuth oxide. It can also react with halogens such as fluorine, chlorine, bromine, and iodine to form bismuth halides.
Which elements found in nature have mainly radioactive isotopes?
Some elements found in nature that mainly have radioactive isotopes include uranium, thorium, and potassium. These elements have naturally occurring radioactive isotopes that decay over time, releasing energy in the form of radiation.
Some elements such as uranium and plutonium are radioactive. These elements decay over time to form?
Radioactive elements like uranium and plutonium decay over time to form more stable daughter isotopes through a process known as radioactive decay. For example, uranium-238 decays into lead-206, while plutonium-239 decays into uranium-235. This process releases radiation in the form of alpha, beta, or gamma particles. Ultimately, these decay chains lead to stable, non-radioactive elements after several steps.

List of radioactive elements?
Elements that decay (give off protons and neutrons) to form other elements. *It's not elements as such that are stable or unstable, but rather isotopes. Even elements of small atomic number have unstable isotopes that undergo radioactive decay, for example carbon-14. Elements with higher atomic numbers than Lead (82) are naturally radioactive in all isotopes. Bismuth (83) has an extremely long half-life, but the time generally becomes shorter (the decay more rapid) as the size of the nucleus gets progressively larger for heavier radioactive elements.
What is the meaning of radionuclide?
The term radionuclide is one we apply to any atom with an unstable atomic nucleus. It's the correct term for radioisotope. These atoms are radioactive, and emit radioactivitywhen they undergo radioactive decay. There are unstable configurations of every element, and a few elements have no stable nuclear configurations at all. These include technetium, promethium, and also bismuth and all the elements with an atomic number greater than that of bismuth, which is 83.
How many elements are in row 15 of the periodic table?
There is no "row 15" in any periodic table I have ever seen. There is a column 15 in a wide form periodic table, which contains the stable elements nitrogen, phosphorus, arsenic, antimony, and bismuth, for a subtotal of 5, and may contain one of the very heavy and radioactive elements recently made.
Is bismuth ionic or covalent?
Bismuth typically forms covalent bonds because it is a metalloid with some properties of both metals and nonmetals. However, in some cases, bismuth can also form ionic bonds when it reacts with highly electronegative elements.
Is neon radioactive?
No radioactive isotopes of neon are ordinarily found in nature. All elements have radioactive synthetic isotopes, however.

Bismuth typically reacts with oxygen to form bismuth oxide. It can also react with halogens such as fluorine, chlorine, bromine, and iodine to form bismuth halides.
How many radioactive elements are discovered uptill now?
There are currently 38 radioactive elements that have been discovered. These elements have unstable nuclei that undergo radioactive decay, emitting radiation in the form of alpha particles, beta particles, or gamma rays.

Which phrase describes one characteristic of radioactive elements?
Radioactive elements undergo spontaneous decay, emitting radiation in the form of alpha, beta, or gamma particles.
Which elements found in nature have mainly radioactive isotopes?
