Can the atomic mass of an element vary? What is the difference between a molecular element and an atomic element? What is the relationship between atomic mass and mass number? What is relative atomic mass? Why is atomic number more important than atomic mass?
How are atomic numbers and mass numbers represented? Atomic number is shown on the periodic table. It is the number with a decimal on the periodic table and is often listed below the symbol for the atom. Mass number is not shown on the periodic table but is often found when elements are...
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...
Neutrons are electrically neutral, they also have a mass of one amu, and they're also located inside the nucleus of the atom. Electrons have a negative charge, have almost no mass, and are located in the very large region outside of the nucleus called the electron cloud. Read Atomic & ...
Answer to: What is the definition and units for atomic mass? What is the difference between molecular mass and nominal mass? Which one do we...
Several direct measurements of the 3H 3He mass difference have been performed by mass spectrometric techniques. It has been suggested that, if a small fraction of the 3He + ions were in the metastable excited state 2 2S 1 2, the mass difference as determined by mass spectrometry would be ...

These have to do with cubic ionic crystals [2,27], with the force and potential from cubic charge and mass distributions [28,29,30,31], and with the electric capacitance of the cube [32,33]. Here, we will discuss the evaluation of the electrostatic interaction energy of two coinciding ...
What is the Difference Between Mass Number and Atomic Mass? Mass Number is the weight of the nucleus of an atom. Atomic Mass is the average weight of an...
