Why was lead taken out of household paints?
lead said

Lead was taken out of paints in the late 1980's because of studies that prove that lead exposure is harmful. Lead can effect virtually all parts of the body. High levels of exposure can cause convulsions, coma, or even death. Low levels of exposure can effect the brain, central nervous system, blood cells, and the kidneys.

What is the single most important use of lead?
lead said

People may say that lead has many different uses and they are all very important in their own ways. However, many agree that the single most important use for lead is lead-acid batteries. Lead-acid batteries are the oldest type of rechargeable batteries. They are also used in motor vehicles such as cars because of their wide range of electric surgical capabilities.

Why does my dentist put a lead blanket on me when I get x-rays?
lead said

When doctors use x-rays, they use radiation with it. The lead blanket protects you from the radiation which may even cause brain damage or other types of radiation poisoning.

Hi! Did you know that when tin and lead react, they form an alloy, pewter?! Do you want to come over and have tea together? We can use my new pewter tea set!

I'm in a relationship with tin because we form pewter which is an alloy in some tea sets.

Together we form a covalent bond with 4 valence electrons each.
