What else can I help you with?
When radioactive isotopes break down into other elements the process is called?
radioactive decay
What elements that emit atomic particles are called?
Elements that emit atomic particles are typically referred to as radioactive elements. These elements undergo radioactive decay and emit particles such as alpha particles, beta particles, or gamma rays as they try to become more stable.
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.
Do all elements have a half-life?
No, not all elements have a half-life. Half-life is a property of radioactive elements that undergo decay over time. Non-radioactive elements do not have a half-life because they do not decay in the same way.
Are gamma rays emitted by radioactive elements?
Yes, gamma rays are a type of electromagnetic radiation emitted by radioactive elements during radioactive decay processes. They are high-energy photons with no mass or charge, and can penetrate through materials easily.
Synthetic elements comprise a majority of which of the following groups?
Synthetic elements comprise a majority of the transactinide elements (elements beyond atomic number 103) in the periodic table. These elements are created artificially in laboratories through nuclear reactions and have very short half-lives due to their instability.
What does the radioactive elements comprise a majority or the periodic table?
All elements after Uranium (U) are radioactive. Much of that is due to the fact that they are so large and unstable, that decay causes more stability. This description ignores complex quantum mechanics such as the weak force, one of the four fundamental forces, driving radioactive decay.
Which group contains only radioactive elements?
The actinoids (formerly actinides) are all unstable metallic elements. The period 7 elements with atomic numbers from 89 (actinium, for which the group is named) through 103 comprise these elements. A link can be found below.
What elements comprise silver?
Silver is an element, there are no other elements in it.
Do trace elements have to be radioactive?
No, trace elements are not necessarily radioactive. A link to a list of elements that have no natural radioactive isotopes is at a related question, below.
What element is radioactive and explosive?
There are at least 50 different elements produced in a nuclear explosion, most are fission products in 2 peaks, some are formed by neutron capture and beta decay. The majority of these are radioactive isotopes of the elements.
What made up all radioactive elements?
After disintegration all radioactive elements are transformed in other elements.
Are all transition elements are radioactive?
Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
The pressure and heat that produces magma are caused in part by?
Radioactive elements
What families have no radioactive elements?
Radioactive elements exist in all groups of the periodic table.
What are elements with no stable isotopes called?
Elements with no stable isotopes are called radioactive elements. These elements spontaneously undergo radioactive decay, which leads to the formation of stable isotopes over time.
What element family have no radioactive elements?
Radioactive elements exist in all groups of the periodic table.
