The First Days!
What is GAS?
The number of electrons that can fit into a d orbital.
What is TWO?
Atomic radius increases as you travel in these two directions on the periodic table.
What are DOWN and LEFT?
His number provides the number of molecules (or really, the number of anything) in a mole.
Who is AMEDEO AVOGADRO?
More molecules: SIX MOLES OF HYDROGEN or THREE MOLES OF OXYGEN.
What are SIX MOLES OF HYDROGEN?
These numbers have an unlimited number of significant figures; the number of inches in one feet is an example.
What are EXACT NUMBERS?
1s2 2s2 2p6 3s2 3p6 4s2 3d8.
What is NICKEL?
Lithium is red, copper is blue. But this one has the greater atomic radius.
He was the father of the periodic table, arguing that elemental properties are dependent on functions of their atomic weights.
Who is DMITRI MENDELEEV?
The sum of the number of protons and neutrons in an atom: Atomic Number or Mass Number
What is MASS NUMBER?
The numerical answer to this question, reported to the correct number of significant digits.
2.71 + 8.991 + (0.31 * 41).
What is 24 (with two significant digits)?
The noble gas shorthand configuration for arsenic.
What is [Ar] 4s2 3d10 4p3?
This group forms "-1" anions, as they are electronegative and one electron away from achieving an octet.
What are HALOGENS?
The relationship between energy and frequency is proportional, with this scientist's number being the constant in the equation.
Who is MAX PLANCK?
The energy needed to strip away a valence electron: electron affinity or ionization energy.
What is IONIZATION ENERGY?
The number you get when converting 39 F to Kelvin. You might want to grab your calculator.
What is 277?
Do you want gains? And do you want gains NOW? If only you could curl one of these orbitals, since it is shaped like a dumbbell.
What are P ORBITALS?
What are TRANSITION METALS?
In Niels Bohr's atomic model, electrons were restricted to these energy states; this meant that they could only exist at discrete orbit levels.
What is QUANTIZED? STATIONARY is also acceptable.
All orbitals are singly occupied before electrons can be paired up: Hund's Rule or Pauli Exclusion Principle.
What is HUND'S RULE?
Unlike water, styrofoam and brick are this type of compound, with properties depending on the quantity of the matter.
What are EXTENSIVE COMPOUNDS?
n = 4, l = 2 yields one of these orbitals. Give the energy level and subshell.
What are 4D ORBITALS?
Lithium, sodium, potassium, rubidium, cesium. Of those elements, this one is the most explosive in water because of how easy it is to steal its valence electron.
What is CESIUM?
This physicist proposed that particles could have wave-like character; he eventually predicted that the wavelength of a particle is inversely proportional to its momentum.
Who is LOUIS DE BROGLIE?
Oxygen: paramagnetic or diamagnetic.
What is PARAMAGNETIC?
