To determine which element is more valuable financially, we can look at their respective current market prices.
Firstly, let's find the market price of gold (Au). As of today, you can easily search for the price of gold online or use financial websites. Gold is often quoted in terms of its price per ounce or per gram.
Next, let's find the market price of platinum (Pt). Similarly, search for the current price of platinum per ounce or per gram.
Comparing the prices, you'll be able to see which element is more valuable financially. Keep in mind that market prices fluctuate over time, so make sure to find the most up-to-date prices.
As for mercury (Hg), it is important to note that it is not commonly traded as a precious metal like gold and platinum. Instead, it is primarily used in industrial applications, such as in thermometers and fluorescent lamps. Due to its toxicity and environmental concerns, the market for mercury is highly regulated, which may make it less valuable or less easily tradable compared to gold and platinum.
