The reason behind the change in sizes of atoms across a period of the Periodic Table should be determined. Concept Introduction: Distance from the nucleus to the valence shell of an atom is said to be its atomic size. For covalently bonded atoms, the atomic radius is defined as the one-half of the distance between the nuclei of bonded atoms.

Question

The periodic table is the most important organizing principle in chemistry. There is a regular progression in the periodic table that reflects a similar regularity in the structures and properties of the different elements. If you know the properties of any one element in a group, you can make a good guess at the properties of every other element in the same group and even the elements in neighboring groups. Familiarizing yourself with the structure and arrangement of the periodic table early on will help you later on in chemistry. Part A Classify the following elements as main group elements, transition metals, or inner transition metals. Drag the appropriate elements to their respective bins. ► View Available Hint(s) Main group elements Submit Ca Sn Fm Pd Zn S Transition metals Inner transition metals Reset Help
