Define "Chemical Bond".

The force that holds two atoms together. 

100

Give common names and its compound. 

Water= H2

Ammonia= NH3 

100

Define "Lewis structure". 

 A way of representing atoms or molecules by showing electrons as dots surrounding the element symbol.

100

Why are molecular shapes important?

Molecular shapes are important in determining macroscopic properties such as melting and boiling points, and in predicting the ways in which one molecule can react with another. 

100

Define "Electronegativity". 

The relative ability of an atom to attract electrons in a chemical bond


200

Explain how an atom gains stability. 

The stability of an atom, ion, or compound is related to its energy; that is, lower energy states are more stable.

200

Draw an example of a Lewis structure. 

*It can be any* (Does not let me insert an image) 

300

Draw an example of a covalent bond. 

*They can draw any* (doesn't let me add an image)

400

What are multiple covalent bonds?

A double covalent bond and a triple covalent bond are examples of multiple bonds.

400

Name 3 covalent compound prefixes.  

Mono

Di

Tetra 

500

Give 2 examples of multiple covalent bonds and a drawing of each. 

A double covalent bond forms when two pairs of electrons are shared between two atoms. For example, atoms of the element oxygen only exist as diatomic molecules. 

A triple covalent bond forms when three pairs of electrons are shared between two atoms. Diatomic nitrogen( N2 ) molecules contain a triple covalent bond.

500

Name 3 covalent compound prefixes and what each represent. 

2= Di 

3= Tri-

4= Tetra
