Everything in the world, all matter that exists, is made up of atoms. Atoms are extraordinarily small. However, there are even smaller particles than atoms. Subatomic particles, such as protons, neutrons, and electrons, were thought to be the smallest particles there were. However, it was discovered that there could be something even smaller. Atoms are made up of two major sections, the nucleus and the electron cloud. Electrons are found in the electron cloud, and the nucleus is made up of protons
There are many complicated ways to describe the atomic model, quantum physics and nuclear physics but this is that fast track plane language version. This is a short and sweet explanation of how we know that stars are made of an atom called hydrogen. This will also explain what atoms are and how we know that. All things that we can see are made up of atoms. Atoms are made of protons, neutrons and electrons. Protons are positively charged, neutrons are not charged and electrons are negatively charged
Atoms are the smallest form of matter. They consist of a nucleus and electrons. The nucleus is the center of mass and doesn't contribute to volume. It's made of protons and neutrons. Electrons create an electronic cloud which determines size and volume of an atom but it doesn't contribute to mass. Electrons occupy orbitals, can be found outside of the nucleus, determine the atomic number of an element, and their units are negatively charged. The ozone layer acts as a protective layer from Earth and
Walker 14423422 An electron is a negatively charged, sub atomic particle. It is a fermion, a particle named after the Fermi-Dirac statistics, which describes the electrons behaviour . Bohr proposed that the electron could move from orbitals. This could explain the spectrum for hydrogen but failed for other elements. The electron has a half integer spin, which leads to intrinsic angular momentum, a feature that all fermions possess. Pauli’s Exclusion principle states that two electrons cannot occupy the
The Elegant Universe by Brian Greene describes things about the universe that most people do not know, from superstring theory to additional dimensions. It describes superstring theory in detail; it describes the basic idea as well as its development through the years up until 1999, when the book was written. It also talks about other dimensions in the universe that are not obvious, which according to superstring theory there are between six and seven of. The book also goes over Calabi-Yau shapes
can measure well over 100 000 times the surface gravity of the Earth. Its average density is over a ton to the cubic centimeter; it is so incredibly dense, in fact, that all the atoms that make it up are packed together as tightly as the laws of Fermion physics will allow, making it a totally incompressible "electron degenerate" gas. This oddball super-dense stellar remnant is called a white
