AI Explain

• Nuclear Charge


  The positive charge of the nucleus of an atom that attracts outermost electrons, leading to cohesive forces in metallic bonding
• Delocalised Electrons


  The free-moving electrons that are not localized between specific atoms, contributing to the strength of metallic bonds
• What are Ionic Compounds?


  
  
• What are the Properties of Ionic Compounds?

  Usually crystalline solids, high melting and boiling points, usually soluble in water, conducts electricity in water or when melted.
• What are Reactive Compounds?

  Tend to react readily with other substances, often releasing heat or light, examples include many organic and some inorganic compounds.
• What is a Crystalline Solid?

  Has a repeating pattern of ions, often resulting from strong electrostatic forces between ions.
• What are Electrostatic Forces?


  Attractive or repulsive forces that arise between charged particles, influencing the behavior of ions in ionic compounds.
• What is an Ion?

  Atoms or groups of atoms that have gained or lost electrons, resulting in a net positive or negative charge.
