An Atom and it's Structure
The dense core of an atom, made of protons and neutrons held together by the strong nuclear force. The number of protons in the atomic nucleus gives a substance its identity as a particular element. Called also atomic nucleus.
Nucleons are a proton or neutron, especially when considered as a components of a nucleus.
A Nuclide is an atomic species in which the atoms all have the same atomic number and mass number.
Nuclide Notation is the same as Isotopic Notation
A proton is an elementary particle that is identical with the nucleus of the hydrogen atom, that along with the neutron is a constituent of all other atomic nucleus.
From the textbook: Protons are positively charged particles found in the nucleus.
A neutron is an uncharged elementary particle that has a that is equal to a proton and is present in all known atomic nuclei the expect hydrogen nucleus.
From the textbook: Neutrons are neutral particles found in the nucleus.
Electrons are negatively charged particles with tiny mass found around the nucleus.
Electron shells are thought as an orbit filled by electrons around an atom's nucleus.
A sublevel is an energy level defined by quantum theory. In chemistry, sublevels refer to energies associated with electrons.
Textbook: A sublevel is a part of an energy level made up of orbitals.
Isotopes are different forms of the same element that have different numbers of neutrons in their nuclei. The identity of an element is defined by its atomic number and its chemistry depends on its number of electrons, so isotopes have identical chemical properties. However, as their masses differ slightly they have different physical properties.
Atomic Number (Z)
The atomic number (Z) is the number of protons in the nucleus.
Mass Number (A)
The mass number (A) is the total number of protons and neutrons in the nucleus.
A positively charged ion
Anion's are negativley charged ions.
