The arc discharge method is the main method for producing Carbon Black. The specific process of the arc discharge method is: place the graphite electrode in a reaction vessel filled with helium or argon gas, and stimulate an arc between the two electrodes. At this time, the temperature can r...
In the 1950s, the development of improved particle accelerators and particle detectors allowed scientists to study the impacts of atoms moving at high energies. From this, the Standard Model of particle physics was developed, which has so far successfully explained the properties of the nucleus, th...

Today, atomic research is focused on studying the structure and the function of matter at the subatomic level. This not only consists of identifying all the subatomic particles that are thought to make up an atom, but investigating the forces that govern them. These include strong nuclear forces...
define valency the combining capacity of an atom is known as its valency. the number of bonds that an atom can form as part of a compound is expressed by the valency of the element. we all know how electrons in an atom are arranged in shells/orbitals. valence electrons are those ...
