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 >
Albert Einstein had many notable discoveries, but he did not split the atom. The atom was split by Ernest Rutherford, a physicist from New Zealand, in 1919.Full Answer >
The third energy level of an atom, referred to as the M shell, can hold a maximum of 18 electrons. The number of electrons that any particular element has in the third level depends on its location on the periodic table and can range from none to 18 electrons.Full Answer >
To draw a Bohr model of an atom, first find the number of protons, neutrons and electrons in the atom from its atomic weight and atomic number. After that, place the neutrons and the protons in the nucleus, and draw the electrons in their designated shells.Full Answer >
