even
If you multiply any even number by an even number, the product is an even number.
There is need for a conjecture. It is an easily proven fact that an even number minus an even number is always an even number.
Your question is incomplete. Adding an even number with an odd number will always result in an odd number. Multiplying an even number with an odd number will always result in an even number.
An odd number plus an odd number will be an even number. Odd number A is (even number + 1) Odd number B is (even number + 1) A + B = (even number + 1) + (even number + 1) = even number + even number + 2 Since all even numbers are divisible by 2 and 2 is divisible by 2, each part of the result is divisible by 2, so the sum as a whole is divisible by 2, which means it is an even number.
6 is an even number. A even number is a number which is divisible by 2 and the resulting quotient is a whole number (not a fraction). 6 is divisible by 2, making it an even number.

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 binding energy per nucleon is a measure of how tightly a nucleus is held together. Nuclei with higher binding energy per nucleon are more stable as they require more energy to break apart. Therefore, nuclei with a higher binding energy per nucleon are more stable and tend to resist undergoing nuclear reactions.
By an even number.
10 protons, 12 neutrons
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.
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.)
Stable xenon fluorides have an even number of fluorine atoms because xenon is in the +2 oxidation state when it forms these compounds. This means it can accept a maximum of 8 valence electrons from fluorine atoms to complete its valence shell, leading to the formation of compounds with an even number of fluorine atoms.
Bismuth-209 is stable because it has an odd number of protons and an even number of neutrons, making it less susceptible to radioactive decay. Additionally, bismuth-209 is the heaviest stable isotope of bismuth, which further contributes to its stability.
all of them - even Inert Gases - they just dont react because they have a stable number of them.
