What are the three Types of Chemical Bonds?
Metallic, Covalent, and Ionic
What is a diatomic molecule? Give an example.
Two atoms of the same element. (Ex: H2, O2, N2,..)
3.5 - 1.2 = 2.3
Ionic
What are the Lines representing in a Lewis dot structure?
These are used to represent an electron pair in a covalent bond
Helium, Neon, Argon, Krypton, Xenon, and Radon.
How many people do snake bites kill on average in Australia every year?
2
What type of structure would be formed from an ionic bonds?
A Crystal Lattice.
What is electronegativity?
The tendency of atoms to attract electrons.
FALSE. Anions gain electrons which makes them bigger than cations.
Draw the Lewis Structure for CO2
What is the chemical name for table salt?
Sodium Chloride
What profession was Queen Elizabeth the 2nd (RIP) trained in during world war 2?
Mechanic.
Which bond transfers electrons?
Ionic bonds.
What are valence electrons?
Electrons that are involved in atomic bonding
What type of bond is between O2?
Non-Polar Covalent
3.5 - 3.5 = 0
Draw the Lewis Structure for NH3
Name the subatomic particles that make up an atom and their charges.
Protons (+)
Neutrons (0)
Electrons (-)
What is the largest organ in the human body?
The skin. (Integumentary System)
What type of bond is a sea of electrons which are shared?
Metallic Bonds
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".
What is a triple bond?
This is a covalent bond where the two elements share three pairs of electrons, or 6 electrons in total.
How many lone pairs would each oxygen atom have in the Lewis structure for O2?
TWO!
What is the pH of a neutral solution if the pH scale is from 1-14?
7! We'll learn this next semester
What is the highest-grossing film of all time in 2022?
Avatar
What is a bond formed when atoms share electrons?
Covalent Bonds
Why do atoms bond?
Atoms tend to form bonds to acquire the stability of a noble gas.
What type of bond is found in HCl?
3.0 - 2.1 = 0.9
Polar Covalent
2 single bonds in total!
If a squirrel travels at 3 acorns per minute, how many acorns will it collect in 5 hours?
3 acorns/minute × 60 minutes/hour × 5 hours = 900 acorns
In what year did the Titanic sink?
