Ionic and Covalent Bonding Properties

Why elements undergo bonding?

• To achieve a fully filled valence shell of electrons

• To have 8 electrons in the last shell.

Ionic compounds are formed between

• metals and metals

• metals and non-metals

• non-metals and non-metals

Covalent compounds are formed between

• metals and metals

• metals and non-metals

• non-metals and non-metals.

what kind of bond is formed between two fluorine atoms ?

• Ionic

• Covalent

What kind of bond is formed between calcium and chlorine?

• Ionic

• Covalent

This picture shows a...

• Ionic Bond
• Covalent Bond
• Both bonds
• Neither bond

Low melting point and low solubility in water are general properties of ______________________ compounds

• ionic

• covalent

• all

Which of the following does not explain a substance displaying a high melting point?

• Strong intermolecular forces between molecules.

• Many strong covalent bonds.

• Strong electrostatic attraction between oppositely charged ions.

• Strong electrostatic attraction between positive ions and delocalized electrons

Why does sodium chloride not conduct electricity in its solid form?

• Ions are in fixed positions and cannot move.

• It contains no free electrons.

• It has a giant lattice structure.

• Ions are mobile and will slide over one another.

Carbon dioxide has a low melting and boiling point because

• a lot of energy is required to change the state of carbon dioxide

• it has strong electrostatic forces of attraction between oppositely charged ions

• little energy is needed to break covalent bonds

• little energy is needed to overcome weak intermolecular forces of attraction
