The law of conservation of charge states that...

• all atoms have more protons than electrons
• only protons can be rubbed off of an atom
• charge cannot be created or destroyed
• charge cannot be transferred 

The reason a charged balloon will stick to a wall is that

• the charge is slightly sticky and acts like glue
• electrons transfer back and forth between the wall and the balloon
• induced opposite charges in the wall are closer than other wall charges
• balloon material simply sticks to walls
