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
