When you rub a balloon against your hair or a sweater, it gains a negative charge due to the transfer of electrons. The salt, being a conductor, is attracted to the balloon due to this charge, creating an electrostatic force that causes the salt to stick to the balloon.

What are some examples of electrostatic?
Examples of electrostatic interactions include the attraction between positively and negatively charged ions in salt crystals, the repulsion between two negatively charged electrons, and the adherence of a balloon to a wall after it has been rubbed against hair and becomes charged.
What effects do oppositely charged particles have on each other?
Oppositely charged particles attract each other due to the electrostatic force. This force causes them to move towards each other and eventually bond together to form neutral compounds, like in the case of ions in salt crystals.
How can buoyancy be manipulated?
Buoyancy can be manipulated by changing the density of the fluid (by adding salt, for example), changing the shape or volume of the object (like adding a balloon to increase volume), or changing the gravitational force acting on the object (by taking it to a different planet with a different gravitational pull).
Why does a grape float in salt water?
A grape floats in salt water because the salt makes the water denser, increasing its buoyant force. This extra buoyant force is enough to counteract the grape's weight, allowing it to float.
Does the ship sink or rise in salt water?
A ship will float higher in salt water compared to fresh water because salt water is denser than fresh water, providing greater buoyant force. This is due to the difference in density between the two types of water.
The atoms in salt are held together by?
Electrostatic force of attraction between oppositely charged ions.
Why is salt a strong bond?
Salt is made up of cations and anions and has a strong electrostatic force of attraction between the positively charged cations and negatively charged anions.
What physical property would useful in the separation of very fine saw dust and salt?
You can either put it in water and the salt will dissolve and the sawdust will float, then you can filter it, or you can take a balloon and rub it on your shirt or hair and hold it above and the sawdust will stick to the balloon.
Are the particles in common salt held by weak attractive forces?
No, the particles in salt are Sodium ions (Na+) and Chlorine ions (Cl-) which are held together by the electrostatic force in ionic bonds which are strong. This is why salt has a high melting point.
What are some examples of electrostatic?
Examples of electrostatic interactions include the attraction between positively and negatively charged ions in salt crystals, the repulsion between two negatively charged electrons, and the adherence of a balloon to a wall after it has been rubbed against hair and becomes charged.
How do you get salt to stick to Homemade popcorn?
Put some jizzle on it then just sprinkle the salt. It will stick really good and the jizzle gives it a nice flavor as well.
What halogens combine to make salt?
Because a strong electrostatic attraction exist between halogens and metals.
What happens to electrons when salt is ls made?
For sodium chloride an electrostatic attraction exist between atoms.
What effects do oppositely charged particles have on each other?
Oppositely charged particles attract each other due to the electrostatic force. This force causes them to move towards each other and eventually bond together to form neutral compounds, like in the case of ions in salt crystals.
What are sodium ions attracted to?
Sodium ions are attracted to negatively charged particles or molecules, such as chloride ions in salt or negatively charged sites on proteins or other biological molecules. This attraction is due to the electrostatic force between positive and negative charges.
What is one stick off butter?
Cream and salt.
Why does a charged balloon attract the salt?
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.
