WebIonic Compound Properties 1. Physical properties of ionic compounds. Due to the presence of the strong force of attraction between the positive and negative ions, ionic compounds are solids and are hard to break. They generally break into pieces when pressure is applied, hence they are considered brittle. 2. Melting and boiling points of … The electron ( e or β ) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron's mass is approximately … See more Discovery of effect of electric force The ancient Greeks noticed that amber attracted small objects when rubbed with fur. Along with lightning, this phenomenon is one of humanity's earliest recorded experiences with See more The Big Bang theory is the most widely accepted scientific theory to explain the early stages in the evolution of the Universe. For the first millisecond of the Big Bang, the temperatures were over 10 billion kelvins and photons had mean energies over a million See more Remote observation of electrons requires detection of their radiated energy. For example, in high-energy environments such as the corona of a star, free electrons form a plasma that radiates energy due to Bremsstrahlung radiation. Electron gas can undergo See more 1. ^ The positron is occasionally called the 'anti-electron'. 2. ^ The fractional version's denominator is the inverse of the decimal value (along with its relative standard uncertainty of 2.9×10 ). 3. ^ Note that older sources list charge-to-mass rather than the modern … See more Classification In the Standard Model of particle physics, electrons belong to the group of subatomic particles called leptons, which are believed to be fundamental or elementary particles. Electrons have the lowest mass of any charged lepton (or … See more Particle beams Electron beams are used in welding. They allow energy densities up to 10 W·cm across a narrow focus diameter of 0.1–1.3 mm and usually … See more • Electronics portal • Physics portal • Science portal See more
