Periodic Table

Members of the families (vertical columns) in the periodic table have similar properties. An electron configuration shows the number of electrons in each orbital in a particular atom. The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons in the nucleus), electron configurations, and recurring chemical properties. These electron configurations show that there are some similarities among each group of elements in terms of their valence electrons.

Noble Gas

  • All are gases
  • Mostly inert (don't react) except under very special circumstance.
  • These elements are very nonreactive. For a long time, the noble gases were called the inert gases, because people thought that these elements wouldn’t react at all.

  • A scientist named Neil Bartlett showed that at least some of the inert gases could be reacted, but they required very special conditions. After Bartlett’s discovery, the gases were then referred to as noble gases.
