(backscattered) Conclusion: The nucleus contains nearly all the mass of the atom in an incredibly small volume. 1 Most of the alpha particles passed straight though. Most of the atom is empty space.

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus ...

An atom becomes radioactive when its nucleus contains too many or too few neutrons. Try to keep the same number of neutrons and protons as you build your atom. If the imbalance is too great ...

The nucleus of each nitrogen atom contains seven protons and seven neutrons. That is, it does until a collision happens. The incoming neutron hitting the nucleus causes a proton to shoot out of ...

Nucleus close nucleusA cell component found in most cells which contains the genetic material (DNA) of the organism and controls the cell’s activities.: In the model, this is the grape.

This nucleus contains specific interactions not present in the native state that, when weakened, slow folding but do not change protein stability. Such a decoupling of folding kinetics from ...
