Which one among the following are the correct symbols for the elements gold, tin and lead, respectively?
Au, Sn, Pb
Chemical symbols are abbreviations used to represent chemical elements. Each element has a unique symbol, which is typically one or two letters derived from its English name or its Latin name. Knowing these symbols is fundamental in chemistry.
We need to find the correct chemical symbols for three specific elements: gold, tin, and lead, in that exact order.
So, the correct symbols in the required order are Au, Sn, and Pb.
Let's look at the options provided and compare them with the correct symbols:
Comparing these with the correct symbols (Au, Sn, Pb), we can see that Option 3 lists the correct symbols for gold, tin, and lead, respectively.
Based on the standard chemical symbols for gold, tin, and lead, the correct set of symbols is Au, Sn, Pb.
Here is a table showing the elements mentioned in the options and their correct symbols to help clarify:
| Element Name | Chemical Symbol | Origin (often Latin) |
|---|---|---|
| Gold | Au | Aurum |
| Tin | Sn | Stannum |
| Lead | Pb | Plumbum |
| Gallium | Ga | Gallia (Latin for France) |
| Antimony | Sb | Stibium |
| Astatine | At | Astastos (Greek for unstable) |
Chemical symbols are a shorthand way for scientists worldwide to refer to elements without language barriers. Some symbols are derived from English names (like H for Hydrogen, O for Oxygen), while many others come from older Latin or Greek names (like Fe for Iron from Ferrum, Na for Sodium from Natrium). This historical connection explains why the symbols for elements like gold (Au), tin (Sn), and lead (Pb) don't directly match their English names. Learning these common symbols is crucial for studying chemistry.
