Why are ionic bonds strong?

• Because they are made of light atoms

• Because ions form molecules

• Because of the attraction between opposite charges

• Because electrons are shared

Which of the following best describes covalent bonding?

Why does water have a low melting point compared to sodium chloride?

• Because water is an ionic compound

• Because water molecules are larger

• Because the forces between water molecules are weak

• Because water has more protons

Which of the following correctly compares ionic and covalent bonds?

• Both are formed by sharing electrons

• Ionic bonds are formed between metals; covalent bonds are formed between metals and nonmetals

• Ionic bonds involve transfer of electrons; covalent bonds involve sharing electrons

• Covalent bonds form lattice structures; ionic bonds form simple molecules
