The kanji 鉛鉛 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side, 钅 (金, radical 167), is the "metal" radical, indicating that the character relates to a metal. The right side, 㕣, is the phonetic component, which provides a hint to the pronunciation. It combines the elements related to "metal" (金) and a component suggesting the sound or a related meaning. Over time, the form of the kanji has evolved to its present shape, while still retaining the original intent of indicating a "metal" and a phonetic element.
