What element is a nonmetal in period 3 atomic mass 12?
No element in period 3 has an atomic mass of 12.
Explain the difference between atomic mass and average atomic mass?
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 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.
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.
What is the atomic mass of an element?

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.
What is the difference between the average atomic mass given on the periodic table and the mass of an atom?
An atomic mass is the mass without any changes to it. average atomic mass is is when you average it up that's all.Added:Atomic mass is the average of the masses of the naturally existing (i.e. mixture of) isotopes of one specific element.The atomic mass number is the sum of the protons and neutrons in the nucleus of an atom (specific for one specific isotope).
How do you find relative isotopic mass?
its the same as the mass number e.g. oxygen(-16) is 16, carbon-12 is 12 but carbon-13 is 13 because it has an extra neutron i think anyway Really? I thought that the relative istopic mass was a ratio of the average atomic mass of the element compared to the average atomic mass of carbon. For example chlorine has an average atomic mass of 37 and carbons atomic mass is 12 so its 37 divided by 12 which is about 3:1.
What is the atomic mass of the carbon?
Carbon is a non meta element. Atomic mass of it is 12.
What is the difference between relative isotopic mass and relative atomic mass?
Atomic Mass is the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.Relative 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.Relative isotopic mass is the mass of an atom of an isotope of an element compared with one-twelfth the mass of an atom of carbon-12.Thus an element will have ONE Relative Atomic Mass but there may be MANY individual Relative Isotopic Masses for an Element (depending on how many Isotopes it has).
