As per Dalton’s atomic theory, the atom is the ultimate particle that makes up all matter and it is indivisible. The discovery of subatomic... View Article
Between the years 1906 and 1914, the American physicist Robert Andrews Millikan devised an experiment to determine the magnitude of the charge of... View Article
Electrons were discovered through a series of experiments involving cathode ray discharge tubes. He constructed a glass tube that was partially... View Article
The atomic mass of an element is the mass of one atom of that element. They can be measured in a fairly accurate manner with the help of mass... View Article
Every unique substance features different properties that are characteristic to it. These properties of matter can be classified as physical... View Article
At a macroscopic level (or a bulk level), all matter can be classified as pure substances and mixtures. Matter classified into each of these... View Article
The three primary states of matter include the solid-state, the liquid state, and the gaseous state. In solids, the individual particles are... View Article
Electroweak symmetry is broken by the Higgs mechanism, which is the reason why the W boson and the Z boson obtain mass and the range of the weak... View Article
The Schwinger effect is a predicted physical phenomenon whereby a strong electric field creates matter. Fritz Sauter originally proposed the... View Article
Answer: VSEPR theory is used to predict molecular shapes. It is based on the assumption that atoms have a tendency to arrange themselves in such... View Article
The enthalpy of a thermodynamic system, denoted by H, can be determined with the help of the following equation:H = U + PVWhere U is the internal... View Article
Thermodynamic enthalpy is a very important quantity since it offers insight into the amount of heat present in a particular thermodynamic system.... View Article
The smallest subatomic particles are quarks and leptons. There exist six known types of quarks and six known types of leptons. These quarks and... View Article
The speed of light (when it is travelling in a vacuum) is 299792 kilometres per second. It is often approximated to 3*108 meters per second.... View Article
Pentavalent coordination compounds have trigonal bipyramidal structures. Since the CO group is a neutrally charged, strong field ligand, it... View Article
