The atomic weight (not mass) of a chemical element is calculated considering the percentage concentatration of natural isotopes and the Atomic Mass (not weight) of each isotope.
Average weight of an element expressed in Atomic Mass units.
The atomic weight (not mass) of a chemical element is calculated considering the isotopic composition of the element and the atomic masses (not weights) of these isotopes.
"The average atomic weight (not mass) of a chemical element is calculated considering the percentage of each natural isotope and the atomic masses of these isotopes."
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.
The atomic weight of the element (syn.: mass number).
Average weight of an element expressed in Atomic Mass units.
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 (not mass) of a chemical element is calculated considering the isotopic composition of the element and the atomic masses (not weights) of these isotopes.
The atomic weight that is listed on the periodic table for each element is the weighted average of the atomic masses of an element's naturally occurring isotopes. So you are describing atomic weight as it is used on the periodic table.
The atomic weight or atomic mass.
This is a chemical element with a specific atomic weight.
This is the atomic weight.
IUPAC proposed the atomic weight (243).
The Atomic Mass of an element is the numerical average of all the masses of the naturally occurring isotopes of that element proportionately. Man made elements do not count in supposedly. IE: If we have an element with atomic weight 100 and we have an isotope of that element with atomic weight 102 and if they occurred equally in nature then the Atomic Mass would be 101.
The average atomic weight of an element is the average of all the known isotopes of that element along with their popularity. It would be calculated by gathering all the known isotopes of one element and individually multiplying them by percentage of occurrence.
The average weight in grams of one mole of the element.
"The average atomic weight (not mass) of a chemical element is calculated considering the percentage of each natural isotope and the atomic masses of these isotopes."
