atomic number lollest




number of protons in nucleus.




valence electrons




electrons in the outermost shell (can be easily shared, gained or lost)




Pauli Exclusion Principle




An atomic orbital may describe at most two electrons, each with opposite spin direction




Aufbau Principle




An electron occupies the lowest-energy orbital that can receive it




electro negativity




A measure of the ability of an atom in a chemical compound to attract electrons




gamma radiation




electromagnetic radiation emitted during radioactive decay and having an extremely short wavelength




covalent bond




A chemical bond that involves sharing a pair of electrons between atoms in a molecule




electrostatic repulsion




Describes a force between particles with opposite electrical charges that causes them to push apart from one another




Daltons Law of Partial Pressures




Total pressure of a gas is equal to the sum of the partial pressure of the component gases




heat of fusion




Amount of energy required to change a substance from the solid phase to the liquid phase.




Le Chateliers Principle




States that if a stress is applied to a system at equilibrium, the system shifts in the direction that relieves the stress.




surface tension




An inward force that tends to minimize the surface area of a liquid; it causes the surface to behave as if it were a thin skin




molarity




A common measure of solute concentration, referring to the number of moles of solute per liter of solution.




viscosity




A liquids resistance to flowing




equilibrium constant




the ratio of product concentrations to reactant concentrations at equilibrium, with each concentration raised to a power equal to the number of moles of that substance in the balanced chemical equation
