Question

• na is a metal • na loses 1 electron; cl gains 1 electron • forms an ionic bond h₂o: • h and o are both nonmetals • electrons are shared • forms a covalent bond with a shape of bent. bond characteristics compared compare ionic and covalent bonds: • ionic bonds: • - __________ structures • - ________ melting points • - conduct when __________ • covalent bonds:

Explanation:

The problem is about comparing ionic and covalent bonds, which falls under Chemistry (a subfield of Natural Science). For ionic bonds:

• Ionic compounds form crystalline structures due to the orderly arrangement of ions.
• They have high melting points because strong electrostatic forces hold ions together.
• They conduct electricity when dissolved in water (aqueous) or molten (liquid state) as ions are free to move.

Answer:

• Ionic Bonds:
• \_\_\_\_\_\_\_\_\_\_\_\_\_ structures: Crystalline
• \_\_\_\_\_\_\_\_\_\_\_\_\_ melting points: High
• Conduct when \_\_\_\_\_\_\_\_\_\_\_\_\_: Dissolved in water (or molten)
