Atomic Structure
The most massive nucleon with a mass of 1.00866u
What is a neutron?
Elements in the leftmost group, very reactive as they have a single electron in their valence shell.
What is (group 1) Alkali Metals
The stationary state of lowest energy.
What is the Ground State?
Above this temp domain coupling is destroyed by the increased thermal oscillations and ferromagnetic material loses its ferromagnetism.
What is Curie Temperature?
Diatomic Molecules in which two atoms are different EX: Carbon Monoxide
Heteronuclear Bonds
Defines the atomic orbitals of an atoms electrons.
What are Quantum Numbers?
Electrical and Thermal Conductivity: Intermediate
Electrical Resistance: decreases with increasing temp
Malleability and Ductility:Brittle
Volatility and melting point: Volatile and Low melting Point
What are Semi metals?
Theory stating most atoms prefer to have eight valence electrons even if this means valence shell is not full.Allows for optimally stable bonding configurations.
What is the Octet Rule?
The second component of the electromagnetic field, Produced by tge electric charges in motion.
What is Magnetic Field?
A process physical or chemical that results in a net increase in thermal energy to the surrounding area.
What is an Exothermic Reaction?
Term used to collectively denote protons and neutrons.
What is the nucleon?
Radioactive elements most of which dont occur in nature but are produced in nuclear reactions.
What is Actinides?
The most probable region in which the electron may be found:highly educated mathematically supported guess
What is Orbit of electrons?
Materials where electron spins do not pair, or cancel, completely. Resulting in strong coupling or interactions between neighboring atoms.
What is Ferromagnetic Materials?
Nonmetallic elements gain electrons to become ngeatively charged ions.
What is an Anion?
The probability that the electron will be found in a small volume surrounding a point.
What is Probability Density
Electrical and Thermal Conductivity: Low
Electrical Resistance: Insensitive
Malleability and Ductility: neither malleable or ductile
Volatility and melting point: Volatile and Low melting Point
What are nonmetals?
The idea that no two electrons in the same atom can have the same set of four quantum numbers
What is the Pauli Exclusion Principle
A physical constant that describes the properties of the magnetic field in a vacuum.
What is Permeability?
The electrostatic force that binds ions together
What is an Ionic Bond?
A theory that provides an explanation on of both the law of constant composition and the law of conservation of mass.
What is Dalton's Atomic Theory?
A substance that can be decomposed into two or more simpler substances only by chemical means.
What is a Compound?
Electrons in the outermost electron shell.
What is Valence Electrons?
The SI unit of the magnetic field.
What is the tesla(T)
The sharing of electrons between two atoms.
What is Covalent Bonds
