Do most elements occurs a mixture of two or more isotopes on nature?

For elements the correct term is atomic weight.
For isotopes the correct term is atomic mass.
The atomic weight is determined considering the isotopic composition of an element and the Atomic Mass of each isotope.

Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons (both with 6 protons)

What form does chlorine occurs in nature?
it occurs as compounds, reacted with other elements, and can be separated through the process of electrolysis
Why silver gold and platinum occurs freely in nature?
Because silver, gold and platinum are no reactive chemical elements.
How do two isotopes differ from one another?
Isotopes of the same element differ in the number of neutrons. Isotopes of different elements differ in the number of protons and neutrons. For instance, carbon-12, a stable form of carbon, has 6 protons and 6 neutrons. Carbon-14, a radioactive form of carbon that occurs in nature, has 6 protons and 8 neutrons. Nitrogen-16, on the other hand, also radioactive and occurring in the primary coolant of nuclear power plants, has 7 protons and 9 neutrons.
Do all the 116 known elements occur naturally on Earth?
No, only the elements up to Uranium (Z=92) occur naturally on Earth. The rest have only been made synthetically, because of their radioactivity which renders them unstable and thus unable to exist naturally. The synthetically made elements are called transuranic elements.
What is form when two substances are in the same container but no chemical reactions occurs?
A mixture
Why is it call periodic tables of elements rather than periodic tables of atoms?
Many elements exist naturally in more than one isotopic form, each of which has a different atomic mass number. However, all of these isotopes have almost identical chemical properties, and it is therefore more useful to chemists to list elements in the table, along with the average atomic mass resulting from any mixture of isotopes that naturally occurs.
Why does radioactivity occur in some elements?
It occurs due to the instability of the element. It is a spontaneous process. Radioactive atoms are known as isotopes.
What form does chlorine occurs in nature?
it occurs as compounds, reacted with other elements, and can be separated through the process of electrolysis
How many diiferent kinds of atoms are in a pure element?
It depends on the element. If only one isotope occurs in nature, then all the atoms in a pure element are the same. However, most elements have two or more stable isotopes, so that there will be more than one kind of atom in most samples of such elements.
How does a reaction occurs?
a chemical reaction occur due to the reactivity nature of the elements to get their stability From maddiswamy09@gmail.com
two elements occur in a nature as liquid?
Only Mercury occurs in nature as a liquid in its elemental state. Bromine is also a liquid element, but does not occur in its elemental form in nature.
Why silver gold and platinum occurs freely in nature?
Because silver, gold and platinum are no reactive chemical elements.
What occurs in natures uncombined elements?
The items that occur in nature as uncombined elements are the noble gases. These gases include xenon, helium, radon, argon, neon, and krypton.
How do two isotopes differ from one another?
Isotopes of the same element differ in the number of neutrons. Isotopes of different elements differ in the number of protons and neutrons. For instance, carbon-12, a stable form of carbon, has 6 protons and 6 neutrons. Carbon-14, a radioactive form of carbon that occurs in nature, has 6 protons and 8 neutrons. Nitrogen-16, on the other hand, also radioactive and occurring in the primary coolant of nuclear power plants, has 7 protons and 9 neutrons.
Is oxygen a element of mixture or is it a electron nuetron or is it a isotopes?
Oxygen is an element. It is made up of 8 protons, 8 neutrons, and 8 electrons. If there is a variation in the number of neutrons it becomes one of oxygen's isotopes. If you are referring to "molecular oxygen," which occurs in our atmosphere, it has the chemical formula O2 and is a compound.
What are the atomic mass of elements rarely whole numbers?
1. First cause: the atomic weight is the sum of the weights of protons, neutrons ans electrons.; they don't have masses as integers.2. Second cause: also occurs the so-called mass defect.Not atomic mass for elements; atomic weight is correct.
What three isotopes that can undergo nuclear fission?
There are many isotopes, especially of the trans-Uranium elements which can undergo nuclear fission. The isotopes which are used in nuclear reactors are Uranium-233, Uranium-235 and Plutonium-239, because these isotopes are more readily available than other fissionable isotopes. Uranium-235 occurs naturally, Uranium-233 can be made by neutron irradiation of Thorium-232 and Plutonium-239 can be made by neutron irradiation of Uranium-238.
