A smaller nucleus is generally more stable. Below are some general rules: # (Except for really small nuclei) All stable nuclei contain a number of neutrons that is equal to or greater than the number of protons. # Nuclei with too few or too many neutrons is unstable. # If a nuclei has even numbers of nucleons, it's generally more stable. # Nuclei with "magic numbers" usually tend to be more stable.
A pairing energy is the extra binding energy associated with pairs of nucleons of the same kind - which results in nuclei which have odd numbers of protons or neutrons having a lower binding energy and being less stable than those with even numbers.
The greater the nuclear binding energy, the more stable the nucleus. Even numbers of nucleons also make the nucleus more stable.
It depends on how picky you want to be. Yes, having the same number of nucleons they have practically the same atomic mass. No, because they don't have exactly the same atomic mass due to differences in the nuclear binding energy (and hence aren't truly "isobars", even though that's what they're called). (NB: this usage of "isobar" is from nuclear chemistry and means "nuclei with the same number of nucleons." It's not the meteorological isobar, which is something quite different and wouldn't make any sense in the context of the question.)
Atoms have the same number of protons, but different numbers of neutrons. This means that the mass number changes, even though the atomic number stays the same. Therefore, the two atoms will still belong to the same element, even though their number of nucleons vary.
Yes. In fact, they can even have two nuclei.
The neutral particles, or neutrons, in an atomic nucleus, increase the attractive force (the strong nuclear force) operating in that nucleus. Neutrons are the glue of the nucleus, they hold it together. Remember that the protons, all of which have positive charges, repel each other. I would like to add that sometimes a heavy nucleus such as U235 will decay when it absorbs a neutron, which is not what you might expect based on my claim that a neutron helps to hold the nucleus together. This happens because the decay products, the daughter isotopes, jointly are more stable than the original isotope. So, you can make a nucleus more stable, but also create the possibility of a still more stable arrangement of daughter isotopes. Adding a neutron means that you have more neutrons with which to assemble other nuclei, from the existing collection of nucleons. And even when an existing nucleus is stable, the phenomenon of quantum tunneling allows it to change to an even more stable state of daughter isotopes.
The number of nucleons in an atom can vary. A nucleon is either of the two components that make up an atomic nucleus. That's either a proton or a neutron. Different atoms have different numbers of nucleons, and even different atoms of a given element can have different numbers of nucleons (because of isotopic variation). Let's look an a couple of examples to make our point.In hydrogen-1, which is the simplest and most common form of hydrogen, there is one proton in the nucleus of the atom. It has 1 nucleon. In hydrogen-2, there are a proton and a neutron in the nucleus, and that's 2 nucleons. In hydrogen-3, there are a proton and two neutrons in that nucleus, and that's 3 nucleons. In helium-3, there are two protons and a neutron in the nucleus, and that's 3 nucleons. You can see what's happening if you think it through.
Why certain nuclei are stable and others are not is still not fully understood today! We know many of the rules, and we know which are stable and which are not, but it's not always well understood why some are stable and some aren't. There are even "magic" numbers of stability! See: http://en.wikipedia.org/wiki/Island_of_stability Just like many elements, there are several stable and non-radioactive isotopes of lead (mass number 204, 206, 207, 208), and then there are many that are radioactive (mass number 200, 201, 202, 203, 205, 210, 211, 212).

all of them - even Inert Gases - they just dont react because they have a stable number of them.
Let's assume the kernel version is 2.1.xy.z. The .1 is the minor version number and if it is even, the kernel is stable. If it is odd, which in this case "1" is odd, it is a development or not stable release.
Yes the company can give bonuses even if the company is not financially stable.
You can't have that combination. Such an atom wouldn't be stable - not even for a tiny fraction of a second.The atomic mass is the sum of the atomic number (i.e., the number of protons), and the number of neutrons.
There is more than one kind of nucleus; the most usual types are cell nuclei and atomic nuclei, and even then, not all cell nuclei and not all atomic nuclei are the same size either. The average size of an animal cell nucleus is 900-1000nm.
If you literally mean "even number", because there aren't always an even number of nucleons (each of which has a mass of about 1 amu), nor is there any special reason there should be.If you mean "whole number" instead, it's because the nucleons have a mass of about 1 amu each, not precisely 1 amu each, with the neutrons being slightly more massive than the protons. The electrons make a (very small) contribution as well.Finally, any given element may be a mixture of isotopes, and even if the isotopes individually did happen to have a whole number mass, the mixture wouldn't. Chlorine, for example, is about 3/4 35Cl and 1/4 37Cl, so it comes out to have an average atomic mass of roughly 35.5.
If you multiply any even number by an even number, the product is an even number.
The question is too vague to answer. All atoms of the same element have the same number of protons (if they had a different number of protons, they'd be a different element). However, they don't have to have the same number of neutrons, and the number of stable isotopes of an element vary depending on what the element is (some elements even have NO stable isotopes; depending on what theory you believe, it's possible that over the very long term no elements are stable... it is, however, true that we don't know of any stable isotopes for elements of higher Z than lead, and it's at least theoretically possible that the "stable" isotopes of lead are actually radioactive with extremely long half-lives).
yes. Diesel is a very stable fuel . it wont even react much when put to a flame!
It is even
Not even close to stable. We are currently printing money with nothing to back it up. This will cause serious inflation and devaluing of the dollar. Hardly stable
Yes, an even number plus an even number is always even. Also, and odd number plus an odd number is always even.
Yes, an even number multiplied by an odd number or an even number will give you an even number.
It is an even number.
