Document Summary
Read and be generally familiar with section 8. 9. Know properties and behaviours of groups but don"t memorize reactions. The electron configuration of an atom is easily ascertained from its position in the periodic table. Elements with the same pattern of valence electron configuration are in the same group. For example, elements in group 2a all have ns2 outer configurations. By having a sound knowledge of how the periodic table is divided up one can write the electron configuration for any atom without even using its atomic number! Write the electron configurations or identify element for the following atoms: One of the most common means of determining the sizes of atoms employs the idea of. Let us assume that atoms are spheres and that when two atoms are bonded together that the surface of the spheres touch. By knowing the bond length of the atomic radius can be found.
