What do most elements contain a mixture of?
Most elements contain a mixture of two or more isotopes.
What are elements with identical number for protons and different number of neutrons called?
The answer you are looking for is "isotopes" HOWEVER, please note you CAN NOT HAVE 2 elements with the same number of PROTONS. This is because the number of protons DEFINES an element. Isotopes are the SAME element but with differing numbers of neutrons.
Mass number of first 20 elements?
Mass number is term used for isotopes, not for elements. And it is boring to list here all the isotopes of the first 20 elements.
How does the total number of elements compare to the total number of compounds?
There are a bit more than 100 elements however there are far, far more than 100 millions compounds, each day more compounds are produced, there are a lot of compounds with unknown structure, not having official names. So the ratio is much bigger than 1 to a million
What are Atoms that vary in the number of neutrons found in their nuclei called?
Different elements with same number of neutrons are known as isotones.
What isotopes are atoms of the same elements with different number of?
Isotopes are atoms of the same elements with different number of neutrons.
What do most elements contain a mixture of?
Most elements contain a mixture of two or more isotopes.
Why the mass number of the same atom of an element is not constant?
Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.
What relationships of isotopes and elements?
An isotope is an atom; a chemical element may be formed from one or more isotopes having the same number of protons and electrons but with different number of neutrons.
What do you think nuclear chemists mean when they say that 8 20 and 50 are magic numbers for isotopes?
It is simply that among period 2 elements, oxygen (8) is one of the elements which has the largest number of isotopes, among period 4 elements, calcium (20) has the largest number of isotopes, and among period 5 elements, tin (50) has the largest number of isotopes. In fact tin has the largest number of isotopes overall.
How do isotopes form?
During some radioactive explosion/exposure the atoms combine and if they stay stable they from with extra amounts of protons. Isotopes are when two or more elements have the same number of protons, but different number of neutrons.
Isotopes of uncharged elements have different numbers of?
Isotopes differ in the number of neutrons they possess.
Which elements have different isotopes?
Many elements have different isotopes: 1) Carbon - Carbon 12, Carbon 14 2) Hydrogen - Protium, Deuterium, Tritium 3) Chlorine - Chlorine 35, Chlorine 37 etc
What is the isotopes number element of calcium chloride?
Isotopes of elements exist. There are no isotopes for compounds and calcium chloride is a compound.
Isotopes of elements?
Uranium has a number of isotopes including U235 and U238, both of which are radioactive
What isotopes of uncharded elements have different numbers?
The atomic number of the isotopes of an element is identical; the mass number is different.
What are elements with identical number for protons and different number of neutrons called?
The answer you are looking for is "isotopes" HOWEVER, please note you CAN NOT HAVE 2 elements with the same number of PROTONS. This is because the number of protons DEFINES an element. Isotopes are the SAME element but with differing numbers of neutrons.
