Transition Metals 8-12

By Group 7

Why are we listed where we are on the Periodic Table?

Group’s position Transition metals 8-12 : (G) 8-12 (P) 4, 5, and 6 : These elements are in the position that they are in because these transition metals represent a transition, which means there is a change from metallic characteristics to non-metal characteristics.p metals

Uses and products of this group

Iron : Is used in building materials

Copper : Used to make water pipes, used in electrical cords

Silver : SIlver is used to make different types of jewelry

Environmental Hazards Caused by the transition metals

Mercury: using mercury in the manufacturing of products gas caused too much to be in the earths atmosphere. this in turn can lead to health problems for humans and animals living in these areas.


It may also be released into bodies of water effecting water quality and safety


Health Hazards caused by the Transition Metals

Iron: too much iron in the body can lead to health problems such as Liver cancer, Diabetes, and Alzheimer disease.

( because you body can only hold so much and organs can become clogged)


Too little iron can cause fatigue, decreased immunity or iron-deficiency anemia, which can be serious if left untreated
