The smallest parts of an atom are fermions, the elementary particles that form the subatomic components in every atom. Atoms, the smallest particle of an element that still retains the properties of the element, are composed of protons, neutrons and electrons. Protons and neutrons can be broken down further into quarks, one type of fermion. Electrons are a class of leptons, the other type of fermion.Know More
Fermions are the building blocks of matter and energy in the universe, and are thought to be the smallest particles that exist. Fermions make up most of what is observed in the universe.
Fermions are divided into two classes: quarks and leptons. There are six types of quarks: up, down, charm, strange, top and bottom. Protons and neutrons are made up of three quarks each. A proton has two up quarks and one down quark, while a neutron has two down quarks and one up quark. Quarks have a fractional electrical charge, but when they combine into hadrons such as protons and neutrons they do so in a formation that results in a net integer electrical charge.
Leptons also have six types, one of which is the electron. Unlike quarks, which always are found in groups, the leptons are solitary particles.Learn more about Atoms & Molecules
The part of an atom that has a negative charge is the electron. Electrons are the subatomic particles that orbit the nucleus of an atom.Full Answer >
With an atomic number of 4, beryllium has four electrons: two electron shells surround the atom's nucleus and two electrons in each shell. Beryllium is a rigid metal with an atomic mass of 9.0122. It is lightweight but strong and hard. It has a grayish-white color, but beryl crystals also form green emeralds and the sky-blue aquamarine gemstones.Full Answer >
A nucleus of an atom can be compared to the sun of a solar system because the nucleus, like the sun, is the largest part of an atom and its electrons orbit around it, much like planets in a solar system. Atoms can also gain or lose electrons similarly to how stars can gain or lose planets.Full Answer >
A valence electron is a type of electron present in an atom that works to aid in the process of chemical bond formation with other atoms. These electrons are present in the outer shell of an atom.Full Answer >
