What is the difference between an atom and an element? A chemist masses out 58.933 grams of cobalt. How many grams of boron would she need to mass out to have the same number of atoms in both samples? Where is most of the mass of an atom located?
An element's atomic mass is equal to the sum of the individual particle masses of an atom. Atoms have three basic particles which include protons, neutrons, and electrons. The standard unit for measuring atomic mass is the Dalton (u). ...

which each atom is joined to the same partner but which differ in their mode of bonding: in one isomer the boron atoms are linked to carbon by double bonds and the molecule is linear, while the other is a carbone with donor-acceptor bonds, and is bent at an almost perfect right angle...
What is the Rutherford model of the atom? Discovery of the Atomic Nucleus: Rutherford discovered the atomic nucleus in 1911 when he attempted to pass a beam of alpha particles through a thin sheet of gold foil. Rather than passing through the sheet unimpeded, some of the alpha particles bounc...
A diamond heat spreader is a sheet of synthetic diamond used to dissipate heat. It is typically placed between a heat source and a heat sink.
