a widely distributed element that forms organic compounds in combination with hydrogen, oxygen, etc., and that occurs in a pure state as diamond and graphite, and in an impure state as charcoal.
energy
the capacity for vigorous activity; available power:
ionic bond
the electrostatic bond between two ions formed through the transfer of one or more electrons.
molecule
the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.
surface tension
the elasticlike force existing in the surface of a body, esp. a liquid, tending to minimize the area of the surface, caused by asymmetries in the intermolecular forces between surface molecules.
matter
that which by integrative organization forms chemical substances and living things
electron
an elementary particle that is a fundamental constituent of matter and existing independently or as the component outside the nucleus of an atom
neutron
an elementary particle having no charge, mass slightly greater than that of a proton, a constituent of the nuclei of all atoms except those of hydrogen
proton
a positively charged elementary particle, a fundamental constituent of all atomic nuclei, having a charge equal in magnitude to that of the electron
elements
one of a class of substances that cannot be separated into simpler substances by chemical means. See also chart under
carbon atom
an atom of carbon
compound molecule
contains at least two different elements
hydrophillic
able to interact with water through hydrogen bonding process
positive charge
atom having a deficiency of electrons
hydrogen bond
A type of chemical bond in which a hydrogen atom that has a covalent link with one of the electronegative atoms F, N, O forms an electrostatic link with another electronegative atom in the same or another molecule.
