the valence shell

What do elements gain or lose valence electrons to do?

fill valence shells

What do elements do to fill valence shells?

gain or lose valence electrons

What are ions?

atoms that gain or lose electrons

What are atoms that gain or lose electrons?

ions

What happens for atoms become ions?

they lose the balance between their protons and electrons

Atoms lose the balance between their protons and electrons to become what?

ions

What are atoms that lose electrons to acquire positive charge become?

What are cations?

atoms that lose electrons to acquire positive charge

cats have paws,

so cations are positively charged
