Foundations of Chemistry
This arises from the sharing of electrons between two atoms.
What is Covalent Bonding (Bond)?
This is the very first element on the Periodic Table! It generally only has one proton, one electron, and one neutron.
What is Hydrogen (H)?
There are reactions involving this substance and its counterpart, Bases. Typically sour in taste, and yields H+ or H3O+ ions.
What is an Acid?
This was Dani's major that he studied at NYU as an undergraduate.
What is Biochemistry?
He's the funny guy that comes to our class sometimes. His name starts with an "L"
Who is Liam? (Aka Mr. Tay)
The current atomic model, basically the successor to the Bohr Model. It emphasizes the probability of spaces electrons occupy, known as orbitals.
What is the Quantum Mechanical Model?
This is a Period 2 element with an atomic mass of about 12 u. It can covalently bond to a wide range of elements, including itself.
What is Carbon (C)?
This is the state of matter where molecules or particles exist with very high energy, allowing them to disperse in an entire space. They have no definite volume or shape.
What is a gas?
Danny or Dani are nicknames for a different name.
Who is Danilo?
Some people say it's part of NYC, but deep down, we all know this county is part of Upstate NY.
What is Westchester (county)?
The conversion factor to convert between mass and amount.
What is the Molar Mass? (M)
This element has the electronic configuration 1s2 2s2 2p6 3s2 3p5.
What is Chlorine (Cl)?
Atoms of the same element may exist with different numbers of neutrons.
What is an isotope?
This is the country that Dani and his family are from. (Shoutout to the national team for defeating those Canadian frauds in this year's Gold Cup tournament).
What is Guatemala?
We took this train once. It betrayed us by going in a completely different direction.
What is the B train?
I kept emphasizing this as a chemical explanation for the pull of electrons exerted from the nucleus versus shielding effects from electrons.
What is Effective Nuclear Charge?
This is a stable, highly unreactive element consisting of three subshells.
What is Neon (Ne)?
Some chemical reactions may run backwards or reverse to a normal forward reaction. In these cases, there exists a balance between the forward and reverse reactions.
What is Chemical Equilibrium?
Oh yea, I teach another class for the younger kids don't I?
What is DSR Biology?
The best neighborhood in NYC. (Not biased whatsoever haha)
What is Flushing?
This is a structure of a molecule involving four electron groups around an atom, with only one of them existing as a lone pair.
What is Trigonal Pyramidal (structure)?
This element is right above Silver in the Periodic Table. Its valence electrons exist in the 3d and 4s orbitals.
What is Copper (Cu)?
These are substances that primarily deal with carbons. Entire classes in college deals with their chemistry, notorious for causing nightmares for the poor college students.
What are Organic compounds/molecules?
This is Dani's favorite soccer/football club (domestic club, not a national team). Aka the greatest team the world has ever seen.
What is Arsenal FC?
This is an important abiotic factor found in ecosystems, especially marine ecosystems. It serves a number of purposes, such as providing a shelter or home for creatures, and increasing the concentration of minerals and nutrients in the water. You can have this as a pet, I guess.
What is a rock? ._.
