alpha particle
a positively charged particle consisting of 2 protons and 2 neutrons.
amphoteric
an ion molecule that can act as an acid or a base
beta decay
a nuclear reaction in which an electron or a positron is absorbed by or emitted from the nucleus of an atom
effusion
the process by which a gas escapes through a pinhole into a region of lower pressure
elastic collision
a collision in which no kinetic energy is lost
ion product constant of water (Kw)
1.0*10-14
network solid
a solid in which every atom is covalently bonded to its nearest neighbors to form an extended array of atoms rather than individual molecules
β- decay
neutron → proton + electron
β+ decay
proton → neutron + positron
diamagnetic
an atom that has all of its electrons spin-paired
paramagnetic
an atom where all the electrons are not spin-paired

reaction if Eo > 0
spontaneous
reaction if Eo < 0
non spontaneous
melting point of ionic compound depends on...
the strength of electrostatic attraction (f=kqq/r^2)
vapor pressure only depends on..
the temperature and intermolecular forces
Van der Waals forcers only occur between what kind of molecules?
neutral
in general, the stronger the lewis acid..
the larger the positive charge and the smaller the ionic radius
what is the volume of 1 mole of a gas at STP?
22.4 L
