Which two subatomic particles are in the nucleus of an atom?

• Protons & Electrons
• Protons & Neutrons
• Electrons & Neutrons

How many protons are in the atom shown? 

• 2
• 3
• 4
• 1

What is the overall charge of an atom? 

• positive
• negative
• atomic
• neutral

How do we know the overall charge of an atom?

• The protons and electrons "cancel" each other out, giving it a neutral charge
• There are always more protons than electrons, so the atom is positive
• There are always more electrons than protons, so the atom is negative
• There are so many neutrons, that the atom has to be neutral. 

the central region of an atom where its neutrons and protons are is its 

• nucleus 
• electron cloud
• core 
• center
