Chapter 6 - The Periodic Table - 6.2 Classifying the Elements - 6.2 Lesson Check: 11

Answer

The periodic table contains much information. It systematically organizes the elements in a fashion that presents the similarities among elements in the same families. Moreover, the periodic table provides for periodic trends that can be visualized as one moves across rows and down columns. The periodic table also contains the chemical symbols of all elements (and often their names), the atomic and mass numbers of each element, and sometimes the way electrons are distributed in the energy levels of the atoms. Periodic tables also usually use some system to show the state of matter displayed by each element at standard conditions. Lastly, the periodic table contains a line that separates nonmetals from metals and shows the metalloids in between the two main groups of elements. Sometimes, periodic tables also use color identification to distinguish the different groups of atoms (halogens, noble gases, transition metals, etc.).
