weighted average of the various iisotopes
An isotopic mixture is a combination of different isotopes of the same element. Isotopes are atoms of the same element with different numbers of neutrons. Isotopic mixtures can have varying ratios of isotopes, which can impact the properties and behavior of the element.
Isotopes are atoms of the same element with different numbers of neutrons. Mixtures, on the other hand, are combinations of different substances that are physically mixed together, but not chemically bonded.
Isotopes
By taking the wieghted averages of naturally occurring isotopes of that element. :)
Number of protons
the atomic number of each isotope-apex;)
Most elements contain a mixture of isotopes, which are atoms of the same element with different numbers of neutrons. Isotopes can have different properties but behave similarly in chemical reactions due to their identical number of protons.
The only way is to look it up. The isotopic ratio can be determined on a mass spectrometer. Most periodic tables will have the atomic mass otherwise Google the element the wikipedia article will have the average mass of the element listed there. A few elements like Lead do have differing isotopic ratios depending where it was mined.
Hydrogen is a non metal element. Mass number of it is 1.
Isotopes of the same element have different number of neutrons.
Polonium is the element in group 16 that has unstable isotopes. It is a radioactive element with no stable isotopes.
Isotopes of the same element have a different number of neutrons.
