* Structure: Salt (sodium chloride, NaCl) is composed of sodium (Na+) and chloride (Cl-) ions. Sodium ions have a positive charge, while chloride ions have a negative charge.
* Electrostatic Attraction: Opposite charges attract. The positive sodium ions are attracted to the negative chloride ions, and vice versa. This attraction is called electrostatic force.
* Crystal Lattice: The strong electrostatic attraction between the ions causes them to arrange themselves in a highly organized, three-dimensional structure called a crystal lattice. This lattice structure is what gives salt its characteristic cubic shape.
Essentially, the salt crystals stick together because of the strong electrostatic forces holding the positively and negatively charged ions in a rigid, organized arrangement.
Think of it like magnets: the north pole of one magnet attracts the south pole of another magnet, causing them to stick together. In the case of salt, the positive and negative charges of the ions act like the north and south poles of a magnet, creating a strong bond that holds the crystal together.
