Gold
In short
Gold is a bright yellow chemical element with the symbol Au and atomic number 79. It is a soft, heavy metal that does not rust or tarnish easily.
In plain words
It is a precious metal used for jewellery and money. Because it stays shiny and does not react with air or water, it is very valuable. It can be hammered into thin sheets or pulled into long wires.
A simple example
A wedding ring made of gold stays bright for decades without needing to be painted or coated. This is because the metal itself does not corrode.
Why it matters
Gold is used as a safe way to store wealth during economic uncertainty. It is also essential in high-end electronics because it conducts electricity very well.
Easy to mix up
Do not confuse gold with brass, which is a cheaper man-made mixture of copper and zinc designed to look like gold.
