Isotopes and Ions

100

This is what you call an atom that has either gained or lost an electron.

What is an ion?

200

This is what you call an atom if it either gains or loses a proton in its nucleus.

What is a new element?

300

This is what you call an atom that has lost an electron and has a positive charge. 

Note: (be specific!)
