chemically active or electrically charged. But radon has a short half-life of only about four days‚ meaning that about half of it will decay within four days‚ producing new‚ even lighter radioactive isotopes of other elements like polonium‚ lead‚ and bismuth. Those isotopes keep decaying‚ until a stable isotope of lead is reached. These radon "daughters" are not noble gasses like radon‚ they are usually ionized when they are produced‚ and they will readily stick to anything nearby‚ like healthy lung tissue

DEVELOPMENT OF THE ATOMIC THEORY Part A: HISTORY * 1869: Mendeleev formulated the Table of the Elements - listing them by their atomic weight and grouping them with similar characteristics. * 1897: JJ Thomson discovered electron and isotopes‚ and invented the mass spectrometer. * 1898: Marie Curie discovered and isolated radium‚ a new element which unprompted disintegrated into other elements. This proved that the atoms of one element at least were not indivisible. * 1911: Ernest

nucleon number. * Use proton number and the simple structure of atoms to explain the basis of the Periodic Table (Ref. Z=1 to 20) * Define isotopes. * State the two types of isotopes as being radioactive and non-radioactive. * State one medical and one industrial use of radioactive isotopes. * Describe radioactive isotopes as a source of energy. eg. 235U * Describe the build-up of electrons in `shells` and understand the significance of the noble gas electronic structures

There are thousands of compounds which have been discovered‚ and are yet to be discovered‚ with all these possible combinations it is necessary to provide order through a systematic naming system. This naming system‚ aside from organization also provides the reader with information about the given element. There are different kinds of compounds‚ ionic‚ covalent‚ and acidic and over all of this the atoms making up the compounds are either binary or polyatomic. The simplest compounds to name are binary
