Answer 1

Common table salt (NaCl) has a high melting point due to its ionic bond with a crystal lattice structure.

Step-by-step explanation:

Common table salt (NaCl) has a high melting point because it forms an ionic bond with a crystal lattice structure. In this structure, each sodium ion (Na+) is surrounded by six chloride ions (Cl-) and each chloride ion is surrounded by six sodium ions. This arrangement forms a strong electrostatic attraction between the positive and negative ions, which requires a significant amount of energy to break apart and melt the solid.
