How do you make an ion? 

An atom loses Electrons

An atom loses Protons

An atom gains Protons

An atom gains Neutrons

An atom loses Neutrons

An atom gains Electrons 

Atoms are composed of three subatomic particles. Select those particles. 

Nucleus 

Electroids 

Neutrons

Electron Cloud 

Protons 

Electrons

Neutrinos 

Select all which are true

Electrons: Have a negative charge 

Neutrons: Are electrically negative 

Electron Cloud: Contains Protons  

Nucleus: Contains protons and neutrons 

Protons: Define the atom 

What is the difference between an atom and an Ion? 

Ions are neutral, but atoms have a charge. 

Atoms are neutral and ions have a charge 

There is not difference between atoms and ions

Atoms have all three subatomic particles, but ions only have electrons 

Indicate which descriptions are true for atoms and ions. 

Protons = Electrons

Lose or gain electrons

Have a charge 

Are neutral
