What 3 families contain no radioactive elements?
Oh, dude, let me break it down for you. So, the three families that contain no radioactive elements are the noble gases, the alkaline earth metals, and the alkali metals. It's like they're the cool kids who don't mess around with that radioactive drama. Just chillin' with their stable atomic structures, you know?
Elements after which element are radioactive?
The atoms that are radioactive are those with unstable nuclei. There is no easy way to tell which is which, so the isotope has to be looked up. All elements have at least some radioactive isotopes. There are 36 elements for which all radioactive isotopes are synthetic or fission products, so for practical purposes, there are no radioactive isotopes of them in nature, except where introduced by human activity. They include most of the common elements we find in nature, but not all. There are 44 elements that are found as stable isotopes, but at least traces of radioactive isotopes are found in nature. Among these are hydrogen, carbon, sodium, silicon, chlorine, and potassium, all of which are necessary for life. Radioactive potassium, in particular, is present as 0.012% of all potassium. For another group of elements, including technetium, promethium, and all with atomic numbers of 83 (bismuth) or more, there is no isotope that is stable.
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 element is radioactive and synthetic plutonium xenon barium or cesium?
Plutonium and xenon are radioactive elements. Plutonium is a synthetic element, while xenon occurs naturally but can also be produced synthetically. Barium and cesium are not synthetic elements but can have radioactive isotopes.
What are the unique properties of actinide metals?
Actinide metals have unique properties including high density, high melting points, and the ability to exhibit multiple oxidation states. They are also radioactive and can undergo fission, making them important for nuclear power generation and weapons production. Additionally, actinides have a variety of magnetic and electronic properties that make them useful in various technological applications.
What made up all radioactive elements?
After disintegration all radioactive elements are transformed in other elements.
What element family have no radioactive elements?
Radioactive elements exist in all groups of the periodic table.
What family is all radioactive elements?
The Actinide series.
What is made up of all radioactive elements?
The actinides
What is unique about elements made in the lab?
All are radioactive, dangerous and unstable
Is a characteristic of Actinides?
All actinides are radioactive elements and some are man made.
Is a characteristic of the actinides?
All actinides are radioactive elements and some are man made.
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.
Radioactive elements comprise a majority?
Radioactive elements make up a small fraction of all naturally occurring elements in Earth's crust. Most elements are stable and non-radioactive. However, even though they are a minority, radioactive elements play important roles in various scientific, medical, and industrial applications.
What families have no radioactive elements?
Radioactive elements exist in all groups of the periodic table.
Are radioactive elements made in a laboratory?
What an interesting question. The answer is however complex.It is possible to make small amounts of some radioactive elements or radioactive isotopes of some elements in a laboratory (usually involving a nuclear pile or an accelerator). For instance the element Plutonium is made this way.(Other radioactive elements are produced naturally by the radioactive decay of heavier radioactive elements)However, making a radioactive element or isotope from scratch requires the application of an enormous amount of energy. The place where all elements heavier than the element Iron (Fe - Atomic number 26) are made is in stellar explosions, the death of stars 8 or more times more massive than our Sun, called "supernovas".It is in supernova explosions that the radioactive elements are made.
The period of elements that are all radioactive?
All elements comprising the period 7 in the periodic table are radioactive. In total this period has 32 elements.
