Electronic materials

 


Electronic materials, electronic materials refer to materials used in electronics and microelectronics, including insulating materials, semiconductor materials, piezoelectric materials, ferroelectric materials, conductive metals, alloy materials, magnetic materials, optoelectronic materials, electromagnetic shielding materials, and other related materials. The link. Material.

 

Electronic materials

It is the material basis for the development of the modern electronics industry, science, and technology, and at the same time, it is a technology-intensive discipline in the field of science and technology.

 

It includes an interdisciplinary knowledge of electronics, physical chemistry, solid-state physics, and process fundamentals.

 

According to the chemical properties of the materials, it can be divided into metallic electronic materials, electronic ceramics, polymer electronics, glass insulators, mica, gas-insulated dielectric materials, inductors, insulating materials, magnetic materials, electronic devices, electrical ceramic materials, protection materials, piezoelectric crystal materials, Electronic fine electronic materials, electronic light building materials, electronic soldering tin materials, PCB manufacturing materials, other electronic materials

 

Atomic particles (components of the atom)

Protons and neutrons are heavier than electrons and settle in the nucleus, which is the center of the atom. Electrons are very lightweight and are found in a cloud that orbits around the nucleus. The radius of the electron cloud is 10,000 times the diameter of the nucleus.

 

Protons and neutrons have roughly the same mass. But a single proton weighs more than 1800 electrons. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same.

 

Adding a proton to the nucleus produces a new, less weighty element, and this is what stars do, while adding a neutron produces an isotope or a heavier version of that element.

 

Protons

Protons are positively charged particles found inside the nucleus of an atom. Rutherford discovered it in his experiments with cathode ray tubes that he conducted between 1911 and 1919. Protons have less mass than neutrons, as they have a relative mass = 0.9986 (compared to if we consider that the mass of a neutron = 1) or about 1.673 x 10-27 kilograms.

 

Electrons in an atom

The electron is small compared to protons and neutrons, it is more than 1800 times smaller than them. If we consider that the mass of the neutron = 1, then the relative mass of the electron = 0.0005439, or about 9.109 x 10-31 kilograms.

 

The electron distribution is the orbital description of the positions of electrons in a typical atom. Using the electronic distribution and principles of physics, chemists can predict the properties of an atom. Such as stability, boiling point, and conduction.
