Particle

 Particle

a particle is a small localized object to which can be ascribed several physical or chemical properties such as volume, density or mass.

 

Atoms consist of a nucleus made of protons and neutrons orbited by electrons. ... We now know that atoms are made up of three particles: protons, neutrons and electrons. which are composed of even smaller particles, such as quarks.

 

Elementary particles

 

Fermions, Bosons, Hypothetical particles, Hadrons, Atomic nuclei, Atoms, Molecules.

 

All matter is made of particles; these can be single atoms or atoms chemically joined to make molecules. ... We call the particle formed when more than one atom is chemically joined a molecule. If the atoms are the same, then it is a molecule of an element. If the atoms are different, then it is a molecule of a compound.

Mineralogy

Image
 Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.   Silicates, oxides, sulfates, sulfides, carbonates, native elements, and halides are all major mineral groups.   Becoming a mineralogist requires at a minimum a college degree and often postgraduate work. Since most mineralogists work in research or teaching a PhD is the commonest degree that is required. To prepare for this you need to take a college preparatory track in high school.   Georg Agricola a name for German scientist Georg Agricola.   A career in geology is well compensated, with a variety of different career paths and job titles. The main types of careers for geologists are in academia, working for the government (USGS), environmental consulting, oil and gas industry, or mining industry.

Magnetism

 Magnetism   is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.   There are six basic types of magnetization: (1) diamagnetism, (2) paramagnetism, (3) ferromagnetism, (4) antiferromagnetism, (5) ferrimagnetism, and (6) superparamagnetism. Diamagnetism arises from the orbiting electrons surrounding each atomic nucleus.   Magnets don't need gravity or air. Instead, their power comes from the electromagnetic field they generate all by themselves. One class of magnets, called electromagnets, does need electricity to work.   Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom. The hyperactivity of these electrons gives magnets t...
