Periodic Table of Elements
Part of the Organic Chemistry 1 Workbook For Dummies Cheat Sheet
Studying the elements of the periodic table is vital for understanding organic chemistry. So that you don't have to memorize each element, they're grouped together by their properties.
Chemistry GlossaryA principle discovered by the Greek mathematician Archimedes which states that the volume of a solid is equal to the volume of water it displaces.
Chemistry GlossaryThe number of protons in the nucleus of an atom.
Chemistry GlossaryA model of atomic structure developed by Niels Bohr, a Danish scientist. In this model, electrons occur in orbits of differing energy levels around the nucleus of an atom.
Chemistry GlossaryThe change in the physical state of matter from a gaseous state to a liquid state.
Chemistry GlossaryThe change in the physical state of matter from a gaseous state to a solid state without ever becoming a liquid. The reverse of sublimation.
Chemistry GlossarySubstances that can conduct electricity either in the molten state or when dissolved in water.
Chemistry GlossaryA method used by chemists to represent electrons in bonding and chemical reactions.
Chemistry GlossaryA measure of an atom’s strength to attract a bonding pair of electrons to itself.
Chemistry GlossaryA method used by chemists to diagram the electrons for an atom (including orbitals and subshells) in bonding and chemical reactions.
Chemistry GlossaryA mixture whose composition varies from position to position within a sample.
Chemistry GlossaryA mixture whose composition is the same from position to position within a sample.
Chemistry GlossaryAtoms of the same element that have varying numbers of neutrons.
Chemistry GlossaryThe sum of the protons and neutrons in a particular isotope; also called atomic weight.
Chemistry GlossarySubstances that do not conduct electricity in the molten state or when dissolved in water.
Chemistry GlossaryA nuclear reaction in which an atom’s nucleus splits into smaller parts.
Chemistry GlossaryA process in which lighter nuclei of atoms join together into a heavier nucleus; essentially the opposite of nuclear fission.
Chemistry GlossaryAny reaction that involves a change in nuclear structure.
Chemistry GlossaryA table that displays all known chemical elements in an arrangement that is based on the properties of the elements; changes over time as new elements are discovered.
Chemistry GlossaryA model of atomic structure that is based on mathematics and can be used to explain observations made on complex atoms.
Chemistry GlossaryThe spontaneous decay of an unstable nucleus in an atom.
Chemistry GlossaryA worldwide measurement system that is based on the older metric system. The SI comes from the French Systeme International.
Chemistry GlossaryThe change in the physical state of matter from a solid state to a gaseous state without ever becoming a liquid (such as dry ice).
Chemistry GlossaryThe electrons in the outermost energy level of an atom, the farthest away from the nucleus.
