atomic number lollest
number of protons in nucleus.
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
An electron occupies the lowest-energy orbital that can receive it
A measure of the ability of an atom in a chemical compound to attract electrons
electromagnetic radiation emitted during radioactive decay and having an extremely short wavelength
A chemical bond that involves sharing a pair of electrons between atoms in a molecule
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.
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
A common measure of solute concentration, referring to the number of moles of solute per liter of solution.
A liquids resistance to flowing
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
