Gram's method Gram method Gram's procedure Gram's stain Gram stain | a staining technique used to classify bacteria, bacteria are stained with gentian violet and then treated with Gram's solution, after being decolorized with alcohol and treated with safranine and washed in water, those that retain the gentian violet are Gram-positive and those that do not retain it are Gram-negative |
accelerator particle accelerator atom smasher | a scientific instrument that increases the kinetic energy of charged particles |
atom bomb atomic bomb A-bomb fission bomb plutonium bomb | a nuclear weapon in which enormous energy is released by nuclear fission (splitting the nuclei of a heavy element like uranium or plutonium ) |
Rutherford atom | first modern concept of atomic structure, all of the positive charge and most of the mass of the atom are contained in a compact nucleus, a number of electrons (equal to the atomic number) occupy the rest of the volume of the atom and neutralize the positive charge |
