Ionic and Covalent characteristics

• Soluble in Water = Ionic
• No crystals = Covalent
• Low melting point = Covalent
• Metal and Non metal = Ionic
• Electronegativity lower than 1.7 = Covalent
• Hard and Brittle = Ionic
• Electronegativity difference higher than 1.7 = Ionic
• Nonmetal and nonmetal = Covalent
• Give/Take of Electrons = Ionic
• Conducts electricity when melted = Ionic
• Crystals = Ionic
• Not soluble in water = Covalent
• High melting point = Ionic
