Final answer:
Lead (Pb) is the material found in batteries and other electrical components, particularly in lead storage batteries for vehicles, but its use is regulated due to toxicity concerns. Option D is correct.
Step-by-step explanation:
The material commonly found in batteries and other electrical components is lead (Pb). Lead is used in the production of various types of batteries, including lead storage batteries which are typically used as the power source in vehicles. These batteries contain six identical cells with a lead anode and a cathode made of lead (IV) oxide.
Moreover, lead's applications extend to scientific electronic equipment, medical devices, and shielding for X-rays and nuclear radiation. Despite its widespread use, lead is known for its toxicity and environmental effects, which have led to regulations limiting its use in certain applications such as house paint and gasoline.
The material found in batteries and other electrical components is lead. Lead is used as the cathode material in lead-acid batteries, which are commonly used as the power source in cars and other vehicles. The anodes in each cell of a lead-acid battery are plates or grids of lead containing spongy lead metal, while the cathodes are grids containing powdered lead dioxide (PbO₂). The electrolyte is an aqueous solution of sulfuric acid.
