Which atoms are least likely to be radioactive?
Atoms with stable nuclei are least likely to be radioactive. Typically, atoms with an even number of protons and neutrons are more stable and less likely to undergo radioactive decay. This includes elements such as carbon-12, oxygen-16, and nitrogen-14.
Which lists correctly orders nuclear reactions from most radioactive waste generated to least waste generated within a given period of time?
Fission reactions Fusion reactions Alpha decay Beta decay
Which energy-level changes for an electron is least energetic?
The transition from one energy level to an adjacent energy level is the least energetic for an electron. This is because the energy difference between the closely spaced energy levels is smaller compared to transitions between energy levels that are further apart.
Which are radioactive elements in periodic table?
All elements have at least some radioactive isotopes. For some elements no radioactive isotopes are known except those that are synthetic (see link to related question below). For some other elements, there are both radioactive isotopes and stable isotopes in nature. (see link to related question below). Some elements only have radioactive isotopes, and these are found in nature in at least trace quantities, they include (ordered by atomic number; those marked with * are normally only found in trace amounts in ore as radioactive decay products, and those with ** are distributed radioactive decay products found in trace amounts): Period 5: technetium* Period 6: promethium*, bismuth, polonium*, astatine*, radon** Period 7: francium*, radium*, actinium*, thorium, protactinium*, uranium, neptunium*, plutonium** The fact that all isotopes of bismuth are radioactive was only recently discovered. Some elements are only know as a result of synthesis by human activity, and these are as follows:Period 7: americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, lawrencium, rutherfordium, dubnium, seaborgium, bohrium, hassium, meitnerium, darmstadtium, roentgenium, copernicium, and anything new that might come along.
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.
Radioactive decay speeds up at higher temperatures?
No, radioactive decay is not affected by temperature, at least, not in anything like a normal range. At millions of degrees, yes, it would speed up.
When the electrostatic force overcomes the force in at least part of the nucleus it is called radioactive decay?
strong
The most common types of radioactive decay least penetrating human tissue to most penetrating?
alpha, beta, gamma
Which atoms are least likely to be radioactive?
Atoms with stable nuclei are least likely to be radioactive. Typically, atoms with an even number of protons and neutrons are more stable and less likely to undergo radioactive decay. This includes elements such as carbon-12, oxygen-16, and nitrogen-14.
Which lists correctly orders nuclear reactions from most radioactive waste generated to least waste generated within a given period of time?
Fission reactions Fusion reactions Alpha decay Beta decay
Which photon would do least damage to the nucleus of one of your cells and why?
Single gamma photons would probably do the worst damage to the cell structure. They are extremely energetic and quite radioactive.
Which noble gas has a radioactive isotope?
Radon is a noble gas and is radioactive. All of the other noble gasses have at least some synthetic radioactive isotopes. Radioactive isotopes of both krypton and argon exist in nature in trace quantities.
Radioactive decay is the most dangerous?
There are three types: Beta decay, alpha decay, and gamma decay/gamma rays. They are all dangerous if exposed to a high amount of radioactive matter. When the radioactive isotope undergoes beta, alpha, and gamma decay, there is an emission of a beta particle, alpha particle, and gamma ray (respectively). In highly radioactive matter, there are often trillions of radioactive isotopes that emit these particles and/or rays - and they are very high-energy once emitted. However, they are only dangerous when exposed to a high amount.
What elements are radioactive?
Answerelements with a nonstable isotope or at least one naturally occurring isotope that is radioactive. AnswerAll elements have radioactive isotopes.There are a lot of radioactive elements: Technetium, Promethium, Polonium, Astatine, Radon, Francium...Here is the whole list: http://periodictable.com/Elements/Radioactive
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.
