Module 4 Physical Science

Define

100

The force of attraction between molecules of different substances so that they tend to stick together. 

What is adhesion?

200

The force of attraction between molecules of the same substance so that they tend to stay together. 

What is cohesion?

300

A chemical bond formed between oppositely charged ions. 

What is an ionic bond?

400

A chemical bond in which two atoms share one or more pairs of valence electrons.

What is a covalent bond?

500

A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared. 

What is a polar molecule? 

What am I?

100

What is the compounds chemical formula? 

ZnO₄

200

If a molecule has two silver atoms (Ag), one oxygen (O) atom, and 6 nitrogen (N) atoms.  What is my chemical formula?

Ag₂ON₆

300

If a molecule has two silver atoms (Ag), one oxygen (O) atom, and 6 nitrogen (N) atoms. How many total atoms are in this molecule?

What is 9?

O₆N₁₄H₅C₂

500

If a molecule has six oxygen (O) atoms, 14 nitrogen atoms (N), five hydrogen atoms (H), and two carbon atoms. How many atoms are in this molecule? 

What is 22?

See the board...

300

When an element gains an electron it is an 

What is an anion?

400

When an atom loses an electron it forms a(n)?

What is a cation?

500

Name two ways an element can achieve a stable electron configuration. 

What is form an ionic bond by transferring electrons or form a covalent bond by sharing electrons?

I'm H2O baby!!

100

The chemical formula for water. 

What is H20?

200

Why are water molecules polar?

Water molecules are polar because the oxygen atom has greater attraction for electrons than the hydrogen atom does.  

300

This causes waters surface tension? 

What is cohesion? 

400

Water is this type of molecule.  Non-polar or polar.

What is polar?

500

Polarity, Adhesion, and Cohesion provide this substance with water this attribute. 

What is waters ability to be a liquid at room temperature?
