What are the basic particles found in the nucleus of an atom?
Protons and neutrons are the basic particles found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. These particles are held together by the strong nuclear force.
What term best indicates the total number of neutrons and protons in a particular isotope of an element?
The atomic mass number is the sum of the protons and neutrons of an element. The protons are given by the atomic number, so the neutrons can be found by subtracting the mass number by the atomic number. Both the mass and atomic numbers can be found on the periodic table.
What is the protons neutrons and electrons of helium?
The number of protons in an element is always the same as the atomic number, which is 2 in the case of helium. (The atomic number is assigned based on the number of protons in an element.) In a neutral atom (one with no charge), the number of electrons equals the number of protons, so it will be 2 electrons also. However, the number of neutrons will vary depending on the isotope (atoms of the same element with different numbers of neutrons). There are two stable isotopes of Helium, 3He and 4He, having 1 neutron and 2 neutrons respectively. Most helium is helium-4, and helium-3 is found as only about one atom in a million.See link below for more information on Helium, as well as the related question below that will show you how to find the number of protons, neutrons, and electrons in any atom.
What subatomic particles could be changed without changing which element the atom?
You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
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.
What argon isotope has 22 neutrons?
neutrons = 22 (for the most stable isotope of argon, Ar-40)
What is an isotope with 14 protons and 16 neutrons?
The natural stable isotope of silicon, 30Si, has 14 protons and 16 neutrons.
How many neutrons can be found in an atom of nitrogen?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element For the most important natural stable isotope of nitrogen - 14N - the number of neutrons is 7.
How many neutrons are present in the nuclei of an iron atoms?
The number of neutrons in an atom of a certain element varies from one isotope of that element to another. Iron has stable isotopes Fe-54, Fe-56, Fe-57 and Fe-58 Fe-54 has 28 neutrons, Fe-56 has 30 neutrons, Fe-57 has 31 neutrons and Fe-58 has 32 neutrons.
How many neutrons does neon have?
Neon has three stable isotopes, and they are 20Ne, 21Ne and 22Ne. They have 10, 11 and 12 neutrons, respectively. There are a number of other isotopes of neon, and they can be found by following the link below to the Wikipedia article on neon.To answer this correctly, it is necessary to know which isotope of neon is considered. Neon has three stable isotopes, and they are Ne-20, Ne-21 and Ne-22. They have 10, 11 and 12 neutrons, respectively.However, if isotope is not mentioned, then the answer will be 10 neutrons for Ne-20 as that is the most abundant isotope of neon.
Neutrons are found in all atoms except for most atoms of nitrogen.?
Neutrons are indeed found in the nuclei of most atoms, including nitrogen; however, the most abundant isotope of nitrogen, nitrogen-14, contains seven neutrons. The statement may refer to the fact that the isotope nitrogen-13, which has only six neutrons, exists but is not stable and is less common. Overall, nitrogen typically has neutrons in its atomic structure.
How many neutrons can be found in an atom of phosphorus?
16 neutrons in P-31 isotope
An isotoe has an atomic number 51 and a mass number 123?
This isotope is antimony-123, which has 51 protons (atomic number) and 72 neutrons (mass number - atomic number). It is a stable isotope of antimony found in nature.
How many protons neutrons and electrons does the isotope Ni-63 have?
Isotope Ni-63 has 28 electrons (it is found by looking at the atomic number for Nickel on the periodic table) and has 35 neutrons (which is found by subtracting the number in the isotope, 63, by the atomic number, 28)
What isotope of uranium has less than 3 neutrons?
None, no element beyond lithium can have a stable isotope with as few as 3 neutrons. If by some happenstance a uranium nucleus did form with as few as 3 neutrons (this would be U95) it would instantly burst apart in a flash of protons before it could even be detected.
How many neutrons are there in calcium?
The most common isotope of calcium (40Ca) has 20 neutrons. You can find this out by subtracting the number of protons (atomic number, 20), from the total AMU's of 40. About 96% of calcium on Earth is calcium-40. Calcium also has eight other isotopes, 41Ca through 48Ca, five of which are radioactive. The second-most prevalent stable isotope is 44Ca which is about 2% of all calcium.
What is the difference between a stable isotope and a unstable isotope?
A stable isotope does not decay and therefore, maintains a constant concentration on Earth. An unstable isotope, also known as a radioactive isotope, decays at a predictable and measurable rate on Earth. An unstable isotope may decay by the ejection of an electron or positron, known as beta decay, or by the ejection of two protons and two neutrons, known as alpha decay.
