The basic structure of an atom consists of a small nucleus located in the center, containing some protons and some neutrons, with electrons orbiting the nucleus.
Most of the stable visible matter in the universe is made out of these particles, each with separate properties.
The proton has a charge of +1.6 times Standard Power of -19, the neutron has no charge, and the electron has a charge of -1.6 times Central Power of -19 coulombs.
The particles electron and positron have some rest energy, typically around 0.511 Mega electron volts.
The wavelength of a photon, when it has a minimum energy, will be a maximum, which can be referred to as Lambda Max.
The energy coming out of a particle will have a certain minimum energy, which can be referred to as e minimum.
The masses of the particles are: the neutron is slightly heavier than the proton, both have a mass of around 1.67 times 10^-27 kg, and the electron has a much lower mass of around 9.11 times 10^-31 kg.
The specific charge is the ratio of the charge of a particle divided by its mass.
The ratio of carbon 14 to carbon 12 in our bodies remains constant after an organism dies.
Physicists can calculate the age of an organism by comparing the percentage of carbon 14 left with isotopic data.
An example of an alpha decay equation is: Uranium 238 emitting an alpha particle and Decaying to thorium, element 19, which means that the nuclear number is going to be 234.
The strong nuclear force is responsible for holding the nucleus together.
Carbon 14 is radioactive and is produced by cosmic rays.
The specific charge of a particle can be measured in units of coulombs per kilogram, often written as kg to the power of minus one.
If the size of the nucleus goes beyond three centimeters, a decay particle is likely to be received because the strong nuclear force can only act within this region.
An exchange particle for any interaction is known as a gauge boson.
The electromagnetic interaction is carried out by these virtual photons.
The strong nuclear force holds the nucleus together.
The electromagnetic force is the force that holds electrons in the atom.
The energy of a photon is equal to HC over Lambda, where H is Planck's Constant and C is the speed of light.
The weak nuclear force is responsible for nuclear decay.
Gravity is a fundamental force that is considerably weaker than the other three interactions and is often ignored in particle physics.
The minimum energy for pair production is the energy of the photon, which is twice the rest energy of the particles.
The interaction between two electrons is carried by a particle known as a virtual photon.
A fundamental force is a force that cannot be broken down into smaller forces.
Examples of fundamental forces include the electromagnetic force, the weak nuclear force, the strong nuclear force, and gravity.
In physics, the relative charge and relative mass are often used in notation, where the proton has a relative charge of +1, the neutron has a relative charge of 0, and the electron has a relative charge of -1.
The total nucleon number, which is the number of protons plus the number of neutrons, is often denoted as 'a'.
In quarks, the barrier number and the strangeness are conserved quantum numbers.
The composition of an anti-particle such as the anti-proton or the anti-neutron should have the same composition but opposite, made out of two anti-downs, one anti-up, resulting in a total charge of zero.
The strangeness quantum number of a strange quark is -1, while that of an anti-strange quark is +1.
The decay of a neutron is the standard beta decay in which a neutron turns into a proton, emitting an electron and an anti-electron neutrino.
During beta minus decay, a down quark in the neutron would have turned into an up quark via the weak nuclear interaction.
A neutron is made of two down quarks and one up quark, resulting in a total charge of +1.
The barrier number of a normal matter quark is +1/3, while that of an antimatter quark is -1/3.
The elementary charge of a neutron is +2/3 e.
The total number of protons in the equation increases by one because the proton number increases by one.
In order to balance the equation, a beta particle, which is an electron with a relative charge of minus one and a nucleon number of zero, is emitted.
The total number of protons in the equation remains constant because a neutron turns into a proton.
The mass of an anti-particle is the same as that of the particle, for example, the electron and the positron have a mass of 9.11 times 10 to the power minus 31 kg, and the positron also has a mass of 9.11 times 10 to the power of minus 31 kg.
