Everything about Atomic Structure
20
Quantum : The amount of energy needed to move an electron from one energy level to another.
Nucleus :The positively charged dense center of an atom.
Isotopes : Atoms of the same element that have different numbers of neutrons.
Frederick Soddy : The person who proposed the idea of isotopes.
Mass number : The total number of protons and neutrons in the nucleus of an atom.
Electron configuration : The arrangement of electrons in the orbitals of an atom.
Aufbau principle : The rule that electrons occupy the orbitals of lowest energy first.
Atomic orbital : A region of space in which there is a high probability of finding an electron.
Atomic number : The number of protons in the nucleus of an atom.
James Chadwick : He discovered the neutron.
Atomic mass : The weighted average of the masses of the isotopes of an element.
Atom : The smallest unit of an element that maintains the properties of that element.
Subatomic particle : A very small particle that is a building block for atoms.
Proton : A subatomic particle that possesses a positive(+) electrical charge.
Ernest Rutherford : He discovered the nucleus.
Neutron : A subatomic particle that has no charge associated with it; that is, it is neutral.
Electron : A subatomic particle that possesses a negative(-) electrical charge.
Niels Bohr : The person who proposed that the electrons aren’t on any random orbit around the nucleus, they are on “special” orbits.
Quarks : components of protons and neutrons.
Electron Subshells : A region of space within an electron shell that contains electrons that have the same energy.
