17.2 Masses of Atoms. Atomic Mass The nucleus contains most of the mass of the atom bc P and N are far more massive than E. P & N are about the same size. Ch. 3 - Atomic Structure II. Masses of Atoms (p.75-80) Mass Number Isotopes Relative Atomic Mass Aver...
Molar mass and moles A mole is a unit used for measuring matter. One mole contains exactly 6.02214076×10²³ elementary entities, which can be atoms, molecules, ions, or other particles (this number is called the [Avogadro's Number]). When we use g/mol, we describe the weight of ...

Hi. I read that the mass of nucleons in nucleus of Oxygen-16 (or nucleus of another atom) is less than the sum of its nucleons if they were separated (also the mass of 8 protons and 8 neutrons). But why does nucleons have less energy in nucleus of atoms than if they were separa...

Atomic massis the sum of the masses of the protons, neutrons, and electrons in an atom, or the average mass, in a group of atoms. However, electrons have so much less mass than protons and neutrons that they don't factor into the calculation. So, the atomic mass is the sum of the ...

Electron capture is most favorable for molecules that have hetero-atoms. For example: nitrogen, oxygen, phosphorus, sulfur, silicon, and especially the halogens: fluorine, chlorine, bromine, and iodine. The presence of oxygen, water, or almost any other contaminant interferes with the electron-...
