What are the three Types of Chemical Bonds?
Metallic, Covalent, and Ionic
100
What is a diatomic molecule? Give an example.
Two atoms of the same element. (Ex: H2, O2, N2,..)
100
What type of bond is found in the MgO?
3.5 - 1.2 = 2.3
Ionic
100
What are the Lines representing in a Lewis dot structure?
These are used to represent an electron pair in a covalent bond
100
Name TWO noble gases.

How many people do snake bites kill on average in Australia every year?
2
200
What type of structure would be formed from an ionic bonds?
A Crystal Lattice.
200
What is electronegativity?
The tendency of atoms to attract electrons.
200
T/F: Anions are SMALLER than cations.
FALSE. Anions gain electrons which makes them bigger than cations.
200
Draw the Lewis Structure for CO2
200
What is the chemical name for table salt?
Sodium Chloride
200
What profession was Queen Elizabeth the 2nd (RIP) trained in during world war 2?
Mechanic.
300
Which bond transfers electrons?
Ionic bonds.
300
What are valence electrons?
Electrons that are involved in atomic bonding
300
What type of bond is between O2?
Non-Polar Covalent
3.5 - 3.5 = 0
300
Draw the Lewis Structure for NH3
300
Name the subatomic particles that make up an atom and their charges.

Electrons (-)
300
What is the largest organ in the human body?
The skin. (Integumentary System)
400
What type of bond is a sea of electrons which are shared?
Metallic Bonds
400
Define Octet Rule
The octet rule states that atoms are most stable when they have eight electrons in their valence shell. This configuration is also known as the "noble-gas configuration".
400
What is a triple bond?
This is a covalent bond where the two elements share three pairs of electrons, or 6 electrons in total.
400
How many lone pairs would each oxygen atom have in the Lewis structure for O2?
TWO!
400
What is the pH of a neutral solution if the pH scale is from 1-14?
7! We'll learn this next semester

500
What is a bond formed when atoms share electrons?
Covalent Bonds
500
Why do atoms bond?
Atoms tend to form bonds to acquire the stability of a noble gas.
500
What type of bond is found in HCl?
3.0 - 2.1 = 0.9
Polar Covalent
500
How many single bonds are in the Lewis Structure for H2O?
2 single bonds in total!
