These are atom from three Noble Gases - Helium, Neon, and Argon. Based on what you know about atomic structure, why are they called "noble" gases?
These elements are "Noble" because with full outer shells, they are not reactive and are stable, reliable, safe.
Aka Noble.
Which atom will be more reactive?
Atom A is more reactive.
This is because A's outer electron shell is almost empty. Atoms whose' outer shells are almost empty or almost full are more reactive.
What is an Ion?
An Ion is an atom that has missing or extra electrons.
An Ion is an atom that has a positive or negative electric charge.
What is the only animal that Mr. Schmid fears?
