WebSpecific charge : e/m ratio is called specific charge and was determined by Thomson as 1.76 × 108 coulombs/gm. Radius : It is of the order 10–15 cm. Density : 2.17 × 1017 g/cc. Mass of electron at speed v is m =. Atomic mass unit : It is 0.0005486 amu. Mass of one mole of electron : It is 0.55 mg. WebAtoms. An atom is the smallest component of an element that retains all of the chemical properties of that element. For example, one hydrogen atom has all of the properties of the element hydrogen, such as it exists as a gas at room temperature, and it bonds with oxygen to create a water molecule. Hydrogen atoms cannot be broken down into ... WebChemistry is based on the modern atomic theory, which states that all matter is composed of atoms. Atoms themselves are composed of protons, neutrons, and electrons. Each element has its own atomic number, which is equal to the number of protons in its nucleus. Isotopes of an element contain different numbers of neutrons. def millwright
