Covalent and Ionic Bonds

What is the main difference between ionic and covalent bonds?

• Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.
• Ionic bonds are stronger than covalent bonds.
• Ionic bonds are found in solids, while covalent bonds are found in liquids.
• Ionic bonds are formed between metals and nonmetals, while covalent bonds are formed between nonmetals only.

What is the role of electronegativity in determining the type of bond that forms between atoms?

• Electronegativity determines the number of electrons an atom will share.
• Electronegativity determines the strength of the bond.
• Electronegativity determines the melting point of the compound.
• Electronegativity determines whether an atom will gain or lose electrons, influencing the type of bond formed.

How do ionic compounds differ from covalent compounds in terms of their physical properties?

• Ionic compounds are always liquids, while covalent compounds are always solids.
• Ionic compounds have lower melting points than covalent compounds.
• Ionic compounds are generally more soluble in water than covalent compounds.
• Ionic compounds have stronger bonds and higher melting points than covalent compounds.
