Ionic Covalent Metallic

A bond between a metal and a nonmetal is called a(n)

• covalent bond

• ionic bond

• metallic bond

• transfer bond

Identify the following compound as ionic, metallic or covalent: MgO

• ionic

• covalent

• metallic

Identify the following compound as ionic or covalent: Na₂SO₄

• ionic

• covalent

This type of bonding can be described as "I give, I get"

• ionic

• covalent

• metallic

What happens to the electrons in a metallic bond?

• They are transferred from one atom to another.

• They are shared between two specific atoms.

• They form a sea of electrons that are free to move.

• They are localized around individual atoms.

Why do ionic compounds conduct electricity when dissolved in water?

• The ions are free to move and carry charge.

• The electrons are free to move and carry charge.

• The molecules are free to move and carry charge.

• The covalent bonds break, allowing charge to flow.

What is the primary reason ionic compounds have high melting points?

• Strong covalent bonds

• Strong electrostatic forces between ions

• Weak van der Waals forces

• Presence of free electrons

• Each atom ends up with a more stable electron arrangement.

• The sodium atom becomes more stable, but the chlorine atom

  becomes less stable.

• The chlorine atom becomes more stable, but the sodium atom

  becomes less stable.

• Each atom ends up with a less stable electron arrangement.
