What is needed to find the average atomic mass of the element?
To find the average atomic mass of an element, you need to know the isotopic masses of each of its isotopes and their relative abundances. Multiply the isotopic mass of each isotope by its relative abundance, then sum these values to calculate the average atomic mass.
What is the mass number of polonium?
Polonium is a metal element. Atomic mass of it is 209.
What letters are used to designate atomic number and mass number in isotopic notation of atoms?
The atomic number is denoted by the letter "Z" and the mass number is denoted by the letter "A" in isotopic notation of atoms.
What is the isotopic symbol of boron?
B is the atomic symbol. a number of different Isotopes exist for this element.6B, 7B, 8B, and so on and so forth.
What is the atomic mass number beryllium?
Berilium is a non metal element. Atomic mass of it is 209.
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 needed to find the average atomic mass of the element?
To find the average atomic mass of an element, you need to know the isotopic masses of each of its isotopes and their relative abundances. Multiply the isotopic mass of each isotope by its relative abundance, then sum these values to calculate the average atomic mass.
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).
What is the mass number of polonium?
Polonium is a metal element. Atomic mass of it is 209.
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.
Is the isotopic mass of given isotope ever an exact while number?
No, the isotopic mass of an isotope is not an exact whole number because it accounts for the average mass of all the isotopes of that element found in nature, which have different masses due to varying numbers of neutrons. The isotopic mass is usually reported as a decimal number.
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 isotopic notation for helium-4?
The isotopic notation for helium-4 is ^4He. This notation denotes the element's atomic number and mass number, which for helium-4 are 2 (atomic number) and 4 (mass number) respectively.
What does the atomic mass tell you about a atom?
The mass.If you also know the element number you can figure out the number of neutrons (provided its an isotopic mass rather than an average mass).
