Ch.7: Ionic Compounds

Ion Know The Formation

100

How should a valence shell appear for any stable element?

The valence shell must be full.

200

DOUBLE Jeopardy! Name a chemical family of elements that become anions to achieve octet stability.

Halogens or Halides

300

What is the term that describes the force of attraction between cations and ions?

Ionic Bond

400

DOUBLE JEOPARDY! What ionic charge can we expect an atom to have if it has 5 valence electrons?

-3 (Gains 3 electrons)

500

TRIPLE JEOPARDY! Why does gaining or losing valence electrons result in an electrostatic charge on an atom?

The number of electrons no longer equals the number of protons, causing an excess of positive or negative charges, thus, an ion is formed.

It's A Salt If You Hit Me

What is a salt?

Any ionic compound!

200

What is an ionic compound?

An ionic compound is any substance composed of atoms (ions) held together by ionic bonds.

300

DOUBLE JEOPARDY! Why do ionic compounds tend to have high melting and boiling points?

The electrostatic attraction between cations and anions is extremely strong. A lot of energy is required in order to break an ionic bond.

400

An unknown substance appears to be a soft, white powder with a low melting point, dissolves in water, and does not conduct electricity when dissolved. Is this substance ionic or not ionic (covalent)?

Not Ionic ... Covalent

500

TRIPLE JEOPARDY!!! What do we call the energy required to separate ions in an ionic crystal?

Lattice Energy
