When was radium discovered? Who are Dmitri Mendeleev and Glenn T. Seaborg? Who discovered uranium's radioactivity? Which element is useful for dating the age of Earth? And why doesn't gold have a scientific name?

    One of the remaining uses of lead is in car batteries. Invented in 1859, the lead-acid battery is relatively cheap and can deliver the high current needed to start an engine. When the battery discharges, electrodes immersed in sulphuric acid are converted to lead sulfate. Charging reverses the process. If the lead sulphate rests for too long, it begins to form crystals, and recharging becomes difficult – this is why it is important to maintain the charge.
