Cb
In short
Cb is the chemical symbol for cobalt, a hard, silvery-grey metal used widely in industry.
In plain words
It is a strong metal that can be turned into many different things. It is often used to make alloys and is very important for making batteries. It also helps create bright colours in glass and ceramics.
A simple example
A rechargeable battery in a smartphone often uses cobalt to help store energy safely. This allows the phone to run for a long time without needing a charge.
Why it matters
Cobalt is essential for the green energy transition because it is a key part of electric vehicle batteries. Without it, making long-lasting batteries for cars and renewable energy storage would be much harder.
Easy to mix up
Do not confuse it with Cu, which is the symbol for copper.
