It is nickel-62 that is most stable atomic nuclei. The reason for this is based on what is in the nucleus of an atom and the way the nucleus of an atom is held together. Put on your thinking cap and let's look into the situation to see if we can make sense of things. We'll back up and do a bit of review.
Protons and neutrons are fused together in atomic nuclei (hydrogen-1 with its lone proton nucleus being the exception). Nuclear binding energy (or residual strong force) holds the protons and neutrons (called nucleons when they are considered part of an atomic nucleus) all together. The strong force, you'll recall, is the force that holds individual quarks and gluons that make up the individual protons and neutrons. The nuclear glue that we mentioned is derived from a small fraction of the mass of eachnucleon, and each of the nucleons has had a bit of its mass converted into this binding energy.
To find the "most stable" atomic nucleus, we need to find the one isotope of the element that has the highest binding energy per nucleon. And that particular isotope is nickel-62. A link can be found below for more information.

∙ 12y agoThe nucleus of an atom is NOT the most stable part of that atom. Many nuclei decay over time into a different type of nuclei. The electrons around the nucleus, on the other hand, remain as electrons forever (as best we can determine).

Most of the mass of an atomic concentrated in the what?
Nucleus.
What provides the stability that occurs in larger atomic nuclei?
The most stable nuclei are iron and nickel, and that is due to the binding energy per nucleon being greatest in that size of nucleus. As you go to heavier nuclei like uranium for instance, the nucleus gets less stable. (see the related Wikipedia link) Larger atomic nuclei (up to lead) are stable because the repulsive electrostatic force does not decrease with distance as greatly as the strong nuclear force does.
What does the subatomic particle do?
Protons and neutrons are the components of the atomic nucleus; the number of protons is equal to the atomic number, the most important parameter for a chemical element. Electrons surround the nucleus and are responsible (the last level) for the chemical properties of elements.
How does binding energy per nucleon effect the stability of a nucleus?
The greater the nuclear binding energy, the more stable the nucleus. Even numbers of nucleons also make the nucleus more stable.
Name the sub atomic particles in an atom?
The most important ones are the proton (positive charge, in the nucleus), the neutron (electrically neutral, also in the nucleus), and the electron (negative charge, goes around the nucleus).
What does it mean if an element is radioacitive?
If an element is radioactive, it refers to the stability of their atomic nucleus. If that atomic nucleus is not stable, it is considered radioactive.
Does an atom become most stable when trying to fill its nucleus?
It becomes most stable when its nucleus is filled, not when it is filling it.
What atom has most stable nucleus Iron or Lead?
Francium has an atomic covalent radius of 260 pm, is radioactive and very unstable.
What is the atomic mass of roentgenium?
The atomic mass of the most stable isotope of Roentgenium is 281. This most stable isotope decays in around 36seconds. Oddly, it's most stable isotope has the same atomic mass as the most stable isotope of the element before: Darmstadtium.
Why some natural occurring element are stable and other are not?
This depends on the ratio protons/neutrons in the atomic nucleus.
Are most atoms their mass number is the same as their atomic number?
No. In most atoms the mass number is at least twice the atomic number. A mass number that is the same as the atomic number would indicate a nucleus with no neutrons. Such a nucleus would be highly unstable except in the case of the hydrogen-1 nucleus, which consists of a single proton. In most other stable nuclei there are at least as many neutrons as their are protons. The mass number is the sum of the number of protons and the number of neutrons.
Most of the mass of an atomic concentrated in the what?
Nucleus.
What are the atomic numbers and mass numbers of the stable and radioactive forms?
1. The atomic number is equivalent to the number of protons in the atomic nucleus of a chemical element. The number of protons is identical for all the isotopes of an element. 2. The mass number is the sum of protons and neutrons in the atomic nucleus of an isotope.
When a nucleus undergoes nuclear decay by gamma rays the atomic number of the element?
nothing, the nucleus just relaxes to a lower energy state that is more stable
What is the difference between the atomic number of an atomand its mass number?
The atomic number is the number of protons in the nucleus of an atom, while the mass number is the sum of the number of protons and the number of neutrons in the nucleus. Only one stable isotope, hydrogen-1, contains no neutrons in its nucleus, so that its atomic number and mass number are both 1. All stable atoms of all other isotopes contain neutrons and therefore will have a mass number larger than their atomic numbers.
What provides the stability that occurs in larger atomic nuclei?
The most stable nuclei are iron and nickel, and that is due to the binding energy per nucleon being greatest in that size of nucleus.

What does the atomic number have to do with a element?
The atomic number represents the number of protons in the nucleus of the given atom. Also, it provides the number of electrons to keep the atom stable (neutral).
