• Nuclear compounds

Ionic compounds form...

• Brittle hard crystals that have high melting points. They conduct electricity when dissolved in water.

• Soft crystals that have low melting points. They don't conduct electricity when dissolved in water.

• Unstable nuclear crystals that have high melting points. They don't conduct electricity in a solid state.

• Brittle hard crystals that have low melting points. They don't conduct electricity when dissolved in water.

Why do elements covalently bond?

• So they can share electrons, and fill both of their valence shells at the same time. They can then become stable.

• So they can receive and gain electrons and become stable

• So they can share electrons, and fill both of their valence shells at the same time. They can then become unstable.

• So they can share electrons, and fill both of their valence shells at the same time. They can then form isotopes.
