What element is used to find the atomic mass of all the elements?
Atomic mass of an element is calculated based on the mass of it's protons and neutrons. This is why we get isotopes. But I think you are talking about Carbon; the periodic table is based on 12.
What element is a nonmetal in period 3 atomic mass 12?
No element in period 3 has an atomic mass of 12.
What is the atomic mass of an element?
The atomic mass of an element is the weight of the constituent atomic paraticles in an atom of a given isotope. The atomic weight is the weighted average mass for atoms in a naturally occurring sample of the element.Almost all of an atom's mass is found in the nucleus, consisting of protons and neutrons.
Atomic mass of an element?
The atomic mass of an element is the relative mass of its atom as compared with the mass of a carbon-12 atom taken as 12 units.
The of an element is defined as the average mass of an atom of the element compared to 112th the mass of an atom of carbon-12. What are the three missing words?
relative atomic mass
What is relationship between atomic mass and average atomic mass?
The average atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. It is, the mass of an atom of the substance, rescaled so that carbon-12 would have a mass of 12.

What has the atomic mass of 12?
Carbon is a non metal element. Atomic mass of it is 12.

relative atomic mass
What does the relative atomic mass of an element tell us about the relative abundance of an isotope?
None. The relative abundance of isotopes is used to calculate the Average Mass (by multiplying the Atomic Mass of the isotopes by their relative abundancies and adding the products together) while the Atomic Mass is simply the number of protons plus the number of neutrons.
How do you calculate the average atomic mass of a element?
The mass of the isotope multiplied by its relative abundance plus the the mass times abundance of other isotopes.(mass of isotope)(relative abundance) + (mass of isotope)(relative abundance) = average atomic massExample: Carbon can be naturally found as carbon- 12 or carbon- 13. The mass of carbon- 12 is 12 amu and it makes up 98.93% of naturally found carbon. The mass of carbon- 13 is 13.00335 amu, and it makes up 1.07% of naturally found carbon. So the equation to calculate the average atomic mass of carbon is:(0.9893)(12 amu) + (0.0107)(13.00335 amu) = 12.01 amu
What is the defined atomic mass in amu of this isotope?
The atomic mass of an isotope is the weighted average mass of all the isotopes of that element based on their natural abundance. It is expressed in atomic mass units (amu).
What is the difference between the average atomic mass given on the periodic table and the mass of an atom?
The average atomic mass on the periodic table represents a weighted average of all isotopes of an element based on their natural abundance, not the mass of a single atom. In contrast, the mass of a specific atom (or isotope) is an exact value for that isotope.
What is the atomic number for an abundant element with mass number 12?
The element with mass number 12 is carbon. The atomic number for carbon is 6.
