Salt is made up of charged ions, namely the sodium (Na+) and chloride (Cl-). The balloon repels one of the two ions, but more strongly attracts the other.
Most of us know how opposite charges attract and like charges repel (if you didn't, you do now), so consider the balloon as being, for instance, positively charged (the charge we choose does not matter, as we simply consider the ions as acting in the opposite manner to how I shall describe). The positive charge pushes the sodium ions in the salt crystals slightly away from it, whilst pulling the negative chloride ions towards it a small amount. It is important to consider only small changes, as the ions are held fairly rigidly in the ionic lattice structure in the salt, and we are not tearing apart the individual components of the crystals with something as rudimentary as an inflated sack of rubber we've been rubbing on our head for a few seconds - think of the chaos. However the difference in distances between the centres of positive and negative charge and the balloon have a significant effect. The centre of positive charge is further from the balloon than the negative charge (though by a small amount). Therefore the force of attraction overcomes that of repulsion, as the magnitude (size) of the force is determined both by the magnitude of the charges involved (which are equal as the overall charge of salt should be 0/uncharged - ie same amount of negative chloride as positive sodium - and the balloon has a charge that is used in both calculations) and on the distance. Think of a magnet and a paperclip: the further you are, the less force between the magnet and paperclip, the closer you are, the greater this force - ie you bring a magnet towards a paperclip in order to lift it up from a table, say. Therefore adding these forces together results in the salt being slightly attracted to the balloon.

Will a balloon attract an aluminum can when charged?
No.
Why a charged balloon does notattract a person's hair if the balloon is far from person's head?
The electric Field repels it but the positively charged balloon is attracted to the negatively charged hair. (opposites attract)
What happens when you try to stick a charged balloon an a metal doorknob?
they will attract
Why the charged balloon wiill be attracted to the charged glass rod?
If charge on the balloon is induced due to the charge of the glass rod then there will be opposite charge and so balloon gets attracted by the rod. Unlike charges do attract each other
Why does rubbing your hair with a balloon cause static electricity?
This has to do with the charge of the objects. Positively charged items stick to negatively charged items (think "opposites attract"). Though objects like hair and balloons are generally neutral (without a charge) and do not attract anything, this can be changed through the transfer of electrons. Electrons are negatively charged subatomic particles that can be transferred between items through contact. When you rub a balloon on your hair, the contact between your hair and the balloon allows electrons to be transferred, known as the triboelectric effect. Some materials are more likely to gain electrons and become more negative, while others are more likely to lose electrons and become more positive. In the case of hair and a balloon, the electrons are transferred from your hair to the balloon, so the balloon becomes negative. Now that electrons have been transferred, your hair and the balloon are of opposite charged and attract one another; therefore, your hair sticks to the balloon. Before the balloon contacts the hair, they both have a stable balance of electrons and protons. Once the balloon is rubbed on the hair, it takes electrons from the hair. Thus leaving the hair positively charged and the balloon negatively charged. Once the balloon is pulled away the hair sticks to it. This happens because opposite charges attract and since the hair was positively charged, and the balloon is negatively charged, they attract.
Why does a balloon stick to the celing when rubbed?
1. Rubbing the balloon to your hair causes the balloon to "steal" electrons from your hair. 2.The balloon has a buildup of electron so it has a negative charge. your hair has lost electrons so it becomes positively charged. 3.Because opposites attract the negatively charged balloon will stick or if there are enough electrons on the balloon they will try and "Jump" the wall and will make a small zap by:Zimran Reubin
What happens when a balloon with a negative charge is brought to the surface of a wall?
i dont know ask your friends at school. if your old, live with it. A Negative Charge or a collection of negative charges will repel other negative charges. A negatively charged balloon will therefore repel those few negative charges in a wall that are capable of moving a little bit. That area of the wall close to the negatively charged balloon will therefore become positively charged. A positively charged wall will attract a negatively charged balloon and the two will stick together.
How can you charge a balloon?
it has a positive charge so the negative item attract to it if it is light enough
Will Salt Sugar Baking Soda Flour Or Baking Soda attract to a balloon?
Ordinary baking Soda usually will if slightly damp, but usually this never works unless the balloon is REALLY staticy....
A balloon will stick to a wooden wall if the balloon is charged?
either negatively or positively charged.
How might you use a balloon with a negative charge to find out whether the charge on another balloon is positive or negative?
If you move a negatively-charged balloon close to another balloon, if it moves towards the first balloon, it is positively-charged. If it moves away, it is negatively charged.
What are gelatin mountains?
static electricity, which is what makes your socks stick to your clothes in the dryer, can be a powereful force. When you rub a piece of wool on a latex balloon, the balloon becomes charged with static electricity. If you hold the balloon near a pile of unflaverd gelitin, the gelitin becomes charged as well, but with the opposite charge. Things that have opposite charges attract, so the geletin starts to creep twords the balloon, trying to make contact
