One twelfth the mass of a carbon 12 atom is used to define an?
One twelfth the mass of a carbon 12 atom is used to define an atomic mass unit (amu) or unified atomic mass unit (u). This unit is used to express atomic and molecular weights on a scale relative to the mass of a carbon-12 atom, making it a common reference point in chemistry.
What term is used to define the way the mass of subatomic particles is described?
The atomic mass or mass of an atom is locaed at the bottom of a sqaure on the periodic table. The atomic mass= atomic number (protons/neutrons)+electrons. Enable to find the number of electrons you must
What is scope of study?
"Scope" defines the paramaters of ..... this can be an object, or a theory process, activity. describing either future,current or past knowledge or statements of descriptive activity, experience etc. Scope always unless of the unlimited nature (specfic) will define specific boundries. Such as a manual is used to define employee duties or company procedures, studies are used to obtain and knowledge to arrive at a logical finishing point. The definitions of scope are the "borders" where the objective, knowledge, instruction or outcome of the activity is found.
How many C atoms of mass 12.00 amu are in 12.00g of carbon?
I am not sure seeing as I am trying to answer that verry question at the moment. However, I believe that it would be 0% because the atomic mass you see on the periodic table is accualy an avrige of cabon 12 amu and all of its isotopes. thus the likleyhood that there is accualy a carbon particle with 12.011 is unlikely. course don't quote me on that im not entierly sure.

What is the process of radiocarbon dating and how does it define the age of organic materials?
Radiocarbon dating is a method used to determine the age of organic materials by measuring the amount of carbon-14 present in a sample. Carbon-14 is a radioactive isotope that decays over time at a known rate. By comparing the amount of carbon-14 in a sample to the amount in the atmosphere, scientists can calculate the age of the material. This process helps archaeologists and scientists date ancient artifacts and fossils.
What isotope defines the atomic mass unit?
Carbon-12 isotope is used to define the atomic mass unit, which is equal to 1/12th of the mass of a carbon-12 atom.
What element has 106 protons and 157 neutrons?
An element with 106 protons is Seaborgium (Sg), which is a synthetic element with the atomic number 106. The number of neutrons, in this case 157, helps to define a specific isotope of Seaborgium. The most common isotope of Seaborgium is Sg-263, which has 157 neutrons.
Define the term isotope explain how two isotopes of an element are different?
Isotopes are atoms of the same element that have different numbers of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers. I hope I helped! ^_^
What element is used to make atomic clocks?
The atom of the isotope caesium 133; the definition of second in SI is based on this atom.
Does one atom of fluorine have more mass than one atom of isotope?
The answer is "which istope of what element?" An isotope of an element is an atom of that element that has the correct number of protons (the "atomic number") which defines the element, and one of a variety of numbers of neutrons. The number of protons plus the number of neutrons in the atom determine the "atomic mass" of that isotope of that element. A "standard" atom of carbon, for example, has 6 protons and 6 neutrons, for an atomic mass of 12 (hence it is called carbon 12) Another isotope of carbon is carbon 14, which has 6 protons to define it as carbon, but has 8 neutrons. It is the same element, with the same chemical properties, but a slightly different mass. The "standard" atom of fluorine has an atomic mass of 19 and an atomic number of 9. This is the only stable sotope of fluorine. Other isotopes can be made, but they decay very rapidly, splitting in to lighter elements and emitting energy as radiation.
What did Niels Bohr define the organization of?
the atomic electrons.
What does the atomic weight mass number of an element represent?
The atomic weight, or atomic mass, of an element represents the average mass of its isotopes, weighted by their natural abundance. It is typically expressed in atomic mass units (amu) and reflects the total number of protons and neutrons in the atomic nucleus, which collectively define the mass number. While the mass number is a whole number indicating the total count of protons and neutrons in a specific isotope, the atomic weight accounts for the relative proportions of all isotopes of the element found in nature.
Which term is used to define define the way the mass of subatomic particles is described?
Atomic Mass units =]
Chemists define gram atomic mass as the number of grams of An element numerically equal to the?
atomic weight

It is to define the elements according to their groups.
Define atomic number?
