So, when the term atomic weight was coined back in 1808, isotopes were unknown and Earth gravity was the norm. The difference between atomic weight and atomic mass became known when F.W. Aston, the inventor of the mass spectrometer (1927) used his new device to study neon. At that time...
When the bonding of atoms takes place either in the same type or different type it forms a molecule for example H2O is a molecule. Molecules are invisible to the naked eye and therefore scientists’ break them down into their atomic parts, for example, water contains two hydrogen atoms and ...
What is the difference between energy and power? What are the different types of mass movements? What is the relationship between moles and atomic mass? What is an Atomic Mass Unit (AMU)? How is average atomic mass calculated? Using the equation for Mass Ratio, what is the mass ratio of...
What is the difference between DNA, chromosomes and genes? What is the average atomic mass of Element X if 51.83% of Element X occurring in nature has a mass of 106.905 amu and 48.17% of the atoms have a mass of 108.905 amu?

Avogadro's Number, while it shares the same numerical value, is often presented in a more historical or traditional context, harkening back to the early days of atomic theory and chemistry when the concept of the mole was not as rigorously defined as it is today. 12 In practical laboratory...
To this aim we have compared the insertion of apolipoproteins A-I and A-II in phospholipid monolayers formed on a Langmuir trough in conditions where lipid packing, surface pressure and charge were controlled. We also used atomic force microscopy to obtain high resolution topographic images of ...
atomic orbitals while ions have either atomic orbitals or molecular orbitals or both atomic and molecular orbitals. This is another difference between atom and ion. Furthermore, atoms can be found only in the gaseous phase, but ions can be found in the gaseous phase, liquid phase and as well...
the equivalent weight of an element is the mass which combines with or displaces 1.008 grams of hydrogen, 8.0 grams of oxygen or 35.5 grams of chlorine. These values are obtained by dividing the atomic mass from the most common valence value; e.g. equivalent weight with regard to oxygen is...
