Write down five atoms that you've interacted with today.

It will depend on what you have done today.

For me (and you will have your own set)

Aluminium (in the drinks can)
Potassium-40 (it was in the banana I had for breakfast)
Carbon (in the plastic in this keyboard)
Nitrogen (in the caffeine in my cup of tea)
Calcium (in the milk in my cup of tea)

But, like I say you will have your own set.

Some of the things are same as my set!!
