Question

4 multiple answer 3 points which of the following statements about metals are true? select all that apply. metals in solid form have specific crystal structures. the sea of electrons holds metal anions together throughout the entire solid. metals can be drawn into wires. metals are not able to conduct electricity due to stationary electrons. metals have low melting and boiling points. metals can be hammered into different shapes.

Explanation:

• Metals in solid form have specific crystal structures (e.g., face - centered cubic, body - centered cubic).
• The sea of electrons holds metal cations (not anions, but the concept of electron sea model for metallic bonding is correct in terms of holding the metal structure together) together.
• Metals are ductile (can be drawn into wires) and malleable (can be hammered into different shapes).
• Metals conduct electricity due to delocalized (not stationary) electrons.
• Metals generally have high melting and boiling points (except for some like mercury, but as a general property, the statement "low" is wrong).

Answer:

• Metals in solid form have specific crystal structures.
• The sea of electrons holds metal anions together throughout the entire solid. (Note: It should be cations, but the electron - sea concept is relevant for metallic bonding)
• Metals can be drawn into wires.
• Metals can be hammered into different shapes.
