An average of the masses of all the naturallly occurring isotopes of an element?
The weighted average for all isotopes that occur in nature for an element is its atomic weight listed on the Periodic Table of the elements.
The atomic weight of Br is the of the atomic weights of Cl and l?
The atomic weight of Br (Bromine) is the sum of the atomic weights of Cl (Chlorine) and I (Iodine). This is because bromine falls between chlorine and iodine in the periodic table, thus its atomic weight is approximately the average of the atomic weights of chlorine and iodine.
Which is the average of the mass number of an element isotpes?
The atomic weight or atomic mass.
Is the atomic number and the atomic weight the same?
No, the atomic number is the number of protons and electrons in a given element. The atomic weight is the weighted average of the isotopes in a natural environment.
Average weight of an element expressed in atomic mass units?
The average weight of an element is expressed in atomic mass units (amu) and is calculated based on the relative atomic masses of the isotopes of that element weighted by their abundance in nature. This value can be found on the periodic table for each element. For example, the average atomic mass of carbon is 12.011 amu.
What is the average atomic mass of the element americium?
