Atoms 1

The positive particles of an atom are 

• electrons 
• positrons 
• neutrons 
• protons 

all matter is made of what 

• energy 
• atoms 
• electrons 
• compounds 

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

• nucleus 
• electron cloud
• core 
• center 

Particles in an atom that are neutral and have no charge are 

• negatrons 
• electrons 
• neutrons 
• protons 

An atoms overall charge is 

• positive 
• depends on its mood 
• neutral 
• negative 

True or False? Neutrons have a negative charge

• True
• False
