Lead Pb

 

Where is lead used--or where does it impact your everyday life?

 

Lead is ued less because of its toxicity

 

Sheets of lead are used as electrodes in car batteries--lead accumulators

 

Diving weights are used by divers to reduce buoyancy--the image shows 0.90 kg (2 lb) and 1.36 kg (3 lb) weights.
