What decay process will an isotope undergo if it lies above the band of stability on a plot of neutrons vs protons?
If an isotope lies above the band of stability on a plot of neutrons vs protons, it will undergo beta decay.
Does Argon Decay?
There are over twenty known isotopes of argon. Of these all but three are radioactive and decay. Of naturally occurring argon, very nearly 100% is not radioactive, with only traces of one radioactive isotope found.
Why are radioisotopes unstable and prone to undergo radioactive decay?
Radioisotopes are unstable because they have an imbalance of protons and neutrons in their atomic nuclei. This imbalance causes them to be prone to undergo radioactive decay in order to achieve a more stable configuration.
What is the relationship between the atomic number the mass and the number of neutrons and protons in an atom?
Glad you asked. Pull up a chair and we'll tackle this one. We need to do a little review before we confront the isotope issue. Ready? Then let's have at it. An atom is an atom, but it becomes a particular element when we know the number of protons in its nucleus. Each element has a unique number of protons in its nucleus, and that is what determines what element it is. Hydrogen has one, helium has two, etc. But the kicker is that, though each element has a specific number of protons, it can have different number of neutrons in the nucleus of one of its atoms and still be that element. Same element (same number of protons), but different numbers of neutrons. Different atomic configurations of a given element are called isotopes of that element. Take helium for example. It has two protons (which is what makes it helium), but it can appear with one or with two neutrons. Each of these is an isotope of helium, and each one is stable, meaning it will not spontaneously undergo any atomic transformation. One other thing is that there are about a million atoms of He-4 for every atom of He-3. There are other isotopes of helium with three, four and more neutrons, but these are artifically made and are unstable. They will decay in a fairly short time. Now we've covered isotopes. The mass number (or atomic mass number or nucleon number) is simply the number of protons plus the number of neutrons in an atom. That's all. If we talk about, say, an atom of U-235, which is a fissionable isotope of uranium, the 235 is the atomic mass number. The element uranium has the atomic number 92, which means that there are 92 protons in its nucleus. If we subtract that 92 from the 235, we get 143 as a result, and that will be the number of neutrons in the nucleus of that isotope of 92U. Simple and easy. One more example. Carbon has an atomic number of 6, and carbon-14 has 14 minus 6 = 8 neutrons in it. Now you've got the scoop on isotopes, mass numbers and neutron counts.
What is the nucleus of argon?
The nucleus contains 18 protons and neutrons. The number of neutrons depends on the isotope of argon. Ar-20, the most common isotope of argon has 22 neutrons.
How man protons does an element have to have to make it radioactive?
An element can be radioactive regardless of its number of protons. Radioactivity depends on the specific isotopes of an element, which can have different numbers of neutrons. Elements with unstable isotopes that undergo radioactive decay typically have too few or too many neutrons compared to the number of protons.
When an isotope is blank it does not undergo radioactive decay?
When an isotope is stable, it does not undergo radioactive decay. Stable isotopes have a balanced number of protons and neutrons in the nucleus, which prevents them from spontaneously changing into another element over time.
A scientists conducts a procedure that's causes nitrogen atoms to gain neutrons. the resulting atoms are?
The resulting atoms are isotopes of nitrogen, specifically nitrogen with a higher mass number due to the additional neutrons. These isotopes may be unstable and can potentially undergo radioactive decay.
What is the meaninq of two isotopes stable and unstable isotopes?
Isotopes are atoms of the same element that have the same number of protons, but different numbers of neutrons, and therefore different masses. Unstable isotopes are radioactive and undergo radioactive decay of their nuclei, while stable isotopes do not undergo radioactive decay.
Do elements often swap neutrons and protons with other elements?
Elements do not typically swap neutrons and protons with other elements. Neutrons and protons are fundamental particles that make up the nucleus of an atom. Elements can undergo radioactive decay, where they may lose or gain protons and neutrons, but this usually results in the transformation of one element into another rather than a direct swap.
What is isotope and radio isotope?
Isotopes are atoms of the same element with the same number of protons but different number of neutrons. Radioisotopes are isotopes that are unstable and undergo radioactive decay, emitting radiation in the process. They are commonly used in medicine, industry, and research.
What decay process will an isotope undergo if it lies above the band of stability on a plot of neutrons vs protons?
If an isotope lies above the band of stability on a plot of neutrons vs protons, it will undergo beta decay.
What is the element formed after atoms have broken down and reformed?
Chemical reaction
If two atoms of uranium have different numbers of neutrons which other properties would be different?
Number of protons in in an element denote the type of element. So you identify element on the number of protons in it. Protons being positively charged can not sit together in a nucleus. They will repel each other. So you do not have an element in which only 2 or more protons and no neutrons are there.It means neutrons act as binding material in an element. So usually equal or more neutrons are there in an element. If same number of neutrons are there in nucleus but different number of protons, then it is no more a same but different element. An element in which different number of neutrons are there are called as Isotope. All element have got one or more Isotopes. So there 'physical' properties would differ but not 'chemical' property.
What are three things can happen to electrons protons and neutrons?
Electrons, protons, and neutrons can undergo several interactions and transformations. They can participate in chemical reactions, where electrons may be transferred or shared between atoms, leading to the formation of bonds. Additionally, protons and neutrons can undergo nuclear reactions, such as fusion or fission, changing one element into another and releasing energy. Lastly, particles can be involved in decay processes, such as beta decay, where a neutron transforms into a proton (or vice versa) while emitting electrons or positrons.
Which of the following element ability to undergo sublimation?
Element iodine has the ability to undergo sublimation, which is the process of transitioning from a solid directly to a gas without passing through the liquid phase.
What is one of the daughter elements of urainium-238?
U238 is a stable isotope of uranium - it doesn't undergo decay except at a very very slow rate unless hit with Neutrons - then it will decay to Neptunium
