Periodic Table

In class we learned about the periodic table and this is what I leaned, 

Organization of table 
  • Yellow is most reactive metals 
  • react in  water to release H2 gas
  •  valence electrons in the outermost energy level groups. 
  • elements in any group of the periodic table have similar physical and chemical properties. 
  • the group provides information about the number of valence electrons. 
  • Halogens are the right side of the chart are non metals they easily combine with other metals.
  • Alkinal Metals are on the left side and are metals they react in water and can not be mixed   
 Parts of table

The rows on a periodic table are called periods going horizontal 
the vertical column are named  families.

Trends 

  • Radius gets larger . left to right 



  • The peaks of the chart are the most reactive metals
