What is the mass number of polonium?
Polonium is a metal element. Atomic mass of it is 209.
What is the atomic mass number beryllium?
Berilium is a non metal element. Atomic mass of it is 209.
The relative abundance of each isotope of an element determines its?
The relative abundance of each isotope of an element is used to determine its atomic mass. This is the weighted average of all naturally occurring isotopes.
What letters are used to designate atomic number and mass number in isotopic notation of atoms?
Each chemical symbol is for a chemical element; each chemical element has a specific atomic number and an atomic weight (not mass, after the rule of IUPAC).
Which gas is heaviest nitrogen hydrogen or oxygen?
Isotopic mas of hydrogen ia '1' Isotopic mass of nitrogen is '14' Isotopic mass of oxygen is '16' It follows that oxygen is the n=heaviest of these gases.
What is the average atomic mass of the element with the isotopic abundances shown?
90.7 amu
How is average weight of atomic mass computed?
the average atomic mass is computed by summing all isotopic weights of the isotopes of that element and then dividing this by the the total number of isotopes of that element (note that isotopic mass is exactly the same as atomic weight, except for isotopes).
What is the atomic mass of poloniun?
Polonium is a metal element. Atomic mass of it is 209.
What is the mass number of polonium?
Polonium is a metal element. Atomic mass of it is 209.
What is the atomic mass of polonuim?
Polonium is a metal element. Atomic mass of it is 209.
What does the atomic mass of an element tell?
The gram atomic weight or gram Atomic Mass of a chemical element is the mass in grams of Avogadro's number of atoms of the element with the isotopic proportions found in nature.
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).
The mass of the mixture of the isotopes for an element?
The mass of the naturally occurring mixture of isotopes for any element is called the atomic weight, whereas the mass of any individual isotope is simply called the isotopic mass.
Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
What is the atomic mass number beryllium?
Berilium is a non metal element. Atomic mass of it is 209.
Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes. The gram atomic mass of each element is the sum of the products of each stable isotope's isotopic fraction multiplied by the mass of that isotope.
What are elements with isotopic atoms?
Elements with isotopic atoms? An isotope is the same form of an element, but with a different number of neutrons. An element with isotopes/"isotopic atoms" is simply an element with isotopes.
