Platinum is a shiny, silver-white metal that is very rare and valuable — even more expensive than gold in a lot of cases. It's used in jewelry, and also in cars and electronics because it doesn't rust or wear out easily. You'll also hear 'platinum' used for a hair color (a very pale, almost white blonde), and in the music industry, an album that sells a huge number of copies is called a 'platinum album.'
白金
組成From Spanish 'platina,' a small word meaning 'little silver' — early Spanish explorers thought it was a lower-quality kind of silver.
