Carbon atom with atomic no of 6 and atomic mass of 12 considered isotopes of one another?
No. A carbon atom has both an atomic number and an atomic mass. All carbon atoms have an atomic number of 6. The most common carbon atom has an atomic mass of 12. See the Related Questions for more information about carbon, isotopes and atomic number and atomic mass.Go to Answers.com and punch in "carbon isotopes" and it will show you various isotopes and the atomic mass (u) associated with each (shown as isotopic mass).
Where does the 0.5 in chlorine's atomic mass come from?
The atomic mass of chlorine is a weighted average of the masses of all its naturally occurring isotopes, taking into account their abundance. Chlorine has two main isotopes, chlorine-35 (with an atomic mass of approximately 34.97) and chlorine-37 (with an atomic mass of approximately 36.97). The 0.5 difference in the atomic mass comes from the relative abundance of these isotopes in nature.
How many neutrons and electrons are in the element chlorine?
Each chlorine atom contains 17 electrons, which offset the electric charge of the 17 protons in the nucleus of each atom, as indicated by the fact that the atomic number of chlorine is 17. The number of neutrons per atom varies, however, depending on which isotope of chlorine is examined. There are two naturally occurring and radioactively stable isotopes of chlorine, with mass numbers of 35 and 37, and there are many other radioactive isotopes. The number of neutrons in an atom of a particular isotope may be found by subtracting 17, the atomic number of chlorine, from the mass number.
Why is relative atomic mass of atoms never a whole number?
The atomic weight is the average weight of an element when all of the isotopes are averaged. This does not mean that there is a portion of a neutron in the atom.. All of the isotopes of an element have a whole number of protons and neutrons. the atomic weight is the average of all the isotopes found, it is affected by the ratios of the different isotopes. If the number was a whole number then no known isotopes have been found.
How many neutrons are in the atom chlorine?
Every chlorine atom has 17 protons; 17 is the atomic number of chlorine. However, chlorine has two isotopes that are stable against radioactive decay. These have mass numbers of 35 and 37, which have 18 and 20 neutrons respectively.
Atomic mass is equivalent to the number of?
The atomic mass is the mass of an atom of that element in AMUs. (Atomic Mass Units)The atomic number, however, is equivalent to the number of protons in an atom of that element.The mass number of an atom is the total number of protons and neutrons in the nucleus of an atom. This is therefore always a whole number. The relative atomic mass of an element is the weighted average of the masses of the isotopes relative to 1/12 of the mass of a carbon-12 atom.It is a weighted average as it takes into account the relative abundances of the different isotopes (atoms of the same element but with different numbers of neutrons) of an element. This number is found in the periodic table.For example chlorine has two isotopes, 35Cl and 37Cl, in the approximate ratio of 3 atoms of 35Cl to 1 atom of 37Cl.The number of protons and neutrons in a 35Cl atom must add up to 35, the mass number. The relative atomic mass of chlorine takes into account both isotopes and is therefore 35.5.
Is sodium and chlorine a pair of isotopes?
Sodium and chlorine are elements. If you mean one sodium atom and one chlorine atom yes they would be both isotopes but of different elemnts. If they were randomly sampled from nature the sodium atom would almost certainly be sodium-23 (there is only a trace of sodium-22 found in nature) and the chlorine atom would most likely be chlorine-35 as this isotope is about 75% of chlorine)
Why does chlorine have an atomic mass of 35.5 write a short example of why this is so using the words protons neutrons isotope atomic number mass number etc?
Chlorine has an atomic mass of 35.5 because the atomic mass of an element is the number of protons plus the number of neutrons. In chlorine, there are always 17 protons (the number of protons in an atom is what makes it whichever element it is), but it is possible to have different amounts of neutrons in the atom. These are called different isotopes of an element. In chlorine, there can be between 17 and 20 neutrons meaning the mass number can range between 34 and 37. The reason that it is written as 35.5 on the periodic table is because that is the average mass number.
State the difference between an ordinary atom and its isotope?
Isotopes: atoms with the same atomic number (also identical number of protons and electrons) but with a different number of neutrons and consequently with a different atomic mass.An isotope is an atom; the atom has not isotopes but an element has isotopes (natural or artificial).
Why is the atomic mass of an atom the average atomic mass?
It allows for the relative abundances of different isotopes.
In the periodic table it lists chlorine what does the number 35.453 mean?
The number that's in the position where chlorine has "35.453" is the average atomic mass in atomic mass units for that element assuming the various isotopes are present in their "natural" ratio. The two common isotoped of chlorine are chlorine-35 and chlorine-37; since in nature there are about 3 35Cl atoms per 37Cl atom, the ratio works out to be distinctly non-integral (also contributing slightly to the non-integral average mass is the fact that the atomic masses of the two isotopes are not EXACTLY 35 and 37).
How many protons are in the atom chlorine?
Atomic number is equal to the number of protons. The atomic number of chlorine is 17. So chlorine has 17 protons.
