Mo6-L5b: How are Metals Grouped?
Key Concept SUMMARY
How Metals are Grouped? How Metals are Grouped?
Alkali metals and alkaline earth metals
What are the group of metals in the periodic table? react easily with other elements. These
metals make up groups 1 and 2 on the
periodic table.
Transition elements make up groups
3-12 and the lanthanide and actinide
series on the periodic table.
