Ionic, Covalent, Metallic Bonds

Ionic

100

What is the metal ion used in this Ionic Bond

PbO

Pb⁺ (Lead Positive 1) 

200

Ionic Bonds are made up of ...

Metals and Nonmetals

300

What must happen to an Ionic Compound before it can be conductive?

Placed in water.

400

Explain how ionic bonds form.

ionic bonds form when one atom gives away electrons to another atom, making both atoms charged (one negative and one positive). These opposite charges attract one another creating a strong bond that holds them together.

500

What is the name of the force that holds ionic bonds together?

Electrostatic Attraction

Covalent

100

Covalent bonds are comprised of only ....

Nonmetals

200

What are the two gasses used in this bond

O₃S

Oxygen and Sulfur

300

What are two properties of Covalent Bonds

- Non-conductive 

- Low melting/boiling point

- Soft texture

- Usually gas or liquid at room temperature.

400

Explain why covalent bonds form between atoms?

Covalent bonds form when atoms share electrons so that each atom can feel like it has a full other shell of electrons. This sharing makes the atoms stick together in a strong bond.

500

Why can covalent compounds not conduct electricity?

There are no charged particles present in the bond, therefore they cannot carry a charge.

Metallic

100

What types of elements combine together to form a metallic bond?

Two or more metals 

200

Which of the following is characteristic of metallic bonds

Brittle

Malleable

High electronegativity difference

Malleable

300

What are the two metals used in this bond,

Al₂Ca

Aluminum and Calcium

400

Explain how metallic bonds form.

Metallic bonds form when metal atoms group together and share their outer elections freely, Instead of each election staying with one atom, the electrons move around all the atoms in a "sea of electrons." This "sea" holds the metal atoms together

500

Why are metals good conductors? (explain using the structure of a metallic bond).

Atoms are packed together closely and their elections can move around freely like a "sea" of electrons which helps them conduct. 

What Bond Is It?

100

NaF

Ionic (Metal and Non-metal)

200

C₂H₆OH

Covalent (Only Non-metals)

300

MgSO₄

Ionic (Metal and Non-metals)

400

An unknown substance is found to be brittle to touch but has a high melting point. What type of bond must it be?

Ionic Bond

500

An unknown substance is conductive in it's solid state at room temperature. What type of bond must it be?

Metallic Bond

Random

100

How many months have 28 days?

All of them.
