Why is it important to use a weighted average when determining the average atomic mass of your element?
It is important to use a weighted average because different isotopes of an element have different atomic masses due to the presence of different numbers of neutrons. The abundance of each isotope also varies, meaning some isotopes are more common than others. By using a weighted average, the more abundant isotopes have a greater contribution to the overall average atomic mass of the element, providing a more accurate representation.
What are some isotopes more heavily weighted than other?
Isotopes contain a different number of neutrons.
Why are some isotopes rarer than others?
Some elements are rarer than others. Elements in the periodic table, up to and including iron can be produced in main sequence stars and these elements are re-distributed into space. Many of them are, therefore, relatively abundant. Elements further up the periodic table are produced in the more cataclysmic supernova explosions and so are rarer. This explains the different abundance of elements.Isotopes can be stable or can decay in fractions of a second or over thousands of years. The decay process produces isotopes of daughter elements. So the abundance of a particular isotope depends on how stable it is, how stable its parent is and on the abundance of its parent.
What is stable and unstable isotopes?
Some isotopes are stable, others are unstable.
How are isotopes different from stable atoms?
Unstable isotopes can spontaneously undergo changes, transforming them into other isotopes of the same or of different elements. Stable isotopes do not. Some isotopes are very unstable and exist for less than a second; others can exist for billions of years but still be unstable. Many elements consist of more than one isotope. One or more of these isotopes may be unstable. In isotopes of an element, the nucleus contains different numbers of neutrons while the number of protons remains the same and determines how the atom behaves chemically. There are several types of instability (too few neutrons, too many neutrons) and several types of decay.
Why is it that some isotopes of an element are able to exist indefinitely?
Some isotypes are more stable than others. Decay occurs because of instability in isotopes, so stable isotopes do not undergo radioactive decay.

Why do some metal corrode while others do not?
All metals corrode under the right conditions only some more easily then others. as it turn out the metals that corrode most easily are usually also the most abundant.

Isotopes contain a different number of neutrons.
What are some of golds isotopes?
Gold has only one stable isotope, all others are radioactive.

Do radioactive isotopes disintegrate easily?
There is a very wide range of half-life for different radioactive isotopes, ranging from the billions of years to very small fractions of a second. So some isotopes disintegrate immediately, and others last a very long time.

Why are some isotopes weighted more heavily than others?
The type of element is decided by the number of protons in it's nucleus. Number of neutrons are either equal or more than number of protons. Mass of proton and neutron is almost equal and that of electron is almost negligible as compared to both of others. As number of neutrons differ, mass of the elements also differ. Though they have 'same' chemical properties. Such atoms with different mass are called Isotopes. If the number of neutron is more, then such Isotopes are having more mass (or weight.)
How many newtrons does krypton have?
The most abundant isotope of Krypton, at 57%, is 84Kr36, which has 48 neutrons. There are other isotopes, some stable and some radioactive. Simply subtract 36 (the number of protons) from the mass number to get the number of neutrons.
Is natural gas abundant?
Abundant means richly supplied so in some places it is easy to find and others, well let say not so much. So the answer is yes and no, how ever, compared to some things in the world it is a no. Also it takes a while to produce, unlike water, it is not so abundant when we run out.
