Electron Configuration, EN and Polarity Determination
Using your EN chart, determine the bond type in NF3
What is 1.0, meaning it is polar covalent?
What is frequency? What is the relationship between wavelength and frequency?
What is the number of cycles of a wave that happen in a unit of time, and an inverse relationship (as wavelength decreases, frequency increases)?
As you move across a period from left to right, atomic radius generally does this.
What is decrease?
Ionic bonds form between these two types of elements.
What are metals and nonmetals?
Name this compound: CO2
Give me the full electron configuration for Nitrogen.
What is 1s22s22p3?
This part of the electromagnetic spectrum has the shortest wavelength and the highest energy.
What are gamma rays?
The ability of an atom to attract electrons in a bond is called _______
What is electronegativity?
Name this compound: Na2O?
What is sodium oxide?
Write the formula for dinitrogen pentoxide
What is N2O5?
Write the abbreviated electron configuration for Sulfur
What is [Ne]3s23p4?
In a PES graph, peaks at a higher binding energy correspond to electrons that are ____________
What is closer to the nucleus?
Explain the rationale for the ionization energy trend (both directions).
What is ionization energy increases from left to right because the nuclear charge pulls the electrons closer, and decreases down a group because there are more energy shells, therefore the electrons are further away from the nucleus?
Write the chemical formula for iron (II) chloride
What is FeCl2?
Briefly explain how the atoms of [what type?] are held together.
What are the metal atoms are held together due the loose hold they each have on their valence electrons, which creates a sea of delocalized electrons that allows for electrostatic attractions?
Give the full and abbreviated electron configuration for V+4
What is 1s22s22p63s23p64s03d1 and [Ar] 4s03d1?
Explain how different metal salts emit distinct colors (using the correct terminology).
What is different metal salts have unique orientations of their corresponding electrons? When these electrons are excited to a different energy level, they will fall down very quickly. Depending on this unique electron orientation, that fall distance will be different, therefore the emission will pertain to a specific wavelength (=color).
Explain the rationale for why Cl has the highest electron affinity instead of F.
What is because chlorine is in the third energy shell, which can hold more electrons than the second energy shell, therefore decreasing the amount of electron-electron repulsion (simply due to the increase of space), so it is more willing to become a negative ion?
Give the name for this: K2SO4
What is potassium sulfate?
Give the molecular formula for this: Hydrosulfuric acid.
What is H2S?
Using dipole moments, please determine the polarity of the following molecule, SO3 (FG will draw on the board)
What is nonpolar?
Draw the photoelectron spectrum (label the axes!) for phosphorus
What is (FG will draw on the board)?
Draw the two other (FG will draw one on the board) resonance structures for carbonate. Additionally, solve for the formal charge for ONE of these structures.
What is (FG will draw on the board)?
Write the chemical formula for this: Manganese (II) phosphate
What is Mn3(PO4)2?
Name the following: HNO3
What is nitric acid?
