Based on the abundance of isotopes, atomic weight is the average of the mass of all the atoms in an element. The atomic mass unit, which is 1/12th the mass of a carbon-12 atom, helps calculate atomic mass and atomic weight. Mass Defect Mass Defect is the difference between the mass...

Also, I thought atomic weight meant the sum of the number of protons and the number of neutrons but I found out that is called the mass number. So how do we find the number of neutrons from a periodic table? Can we simply subtract the atomic weight/atomic mass/ atomic relative mass ...
atomic weight,relative atomic mass mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8...
Fourth, the term atomic weight vs the term atomic mass is discussed shortly, in agreement with the SI system of units and in contrary to the questionable IUPAC convection.doi:10.2298/JMMB111024014KG. KaptayTechnical Faculty in BorJournal of Mining & Metallurgy...
atomic weight 听听怎么读 英[əˈtɔmik weit] 美[əˈtɑmɪk wet] 是什么意思 n. 原子量,各种元素原; 英英释义 atomic weight n.(chemistry) the ratio of the atomic mass of an element to half the atomic mass of carbon 同义词:relative atomic mass...
Standard Atomic Weight- This is the expected atomic weight or relative atomic mass of an element sample in the Earth's crust and atmosphere. It is an average of relative isotope masses for an element from samples collected all over the Earth, so this value is subject to change as new eleme...
If you find an element that exists as only one isotope, then the atomic mass and the atomic weight will be the same. Atomic mass and atomic weight may equal each other whenever you are working with a single isotope of an element, too. In this case, you use the atomic mass in calculat...
