Whats the noble-gas core electron configuration for V3+
[Ar]3d2
which prefers the softer acid OH- or SH-
What is SH-
tell me 3 things Pb has been used for
What are:
1. Paint
2. Bullets
3. Batteries
what orbital forms better pi bonds 2p or 4p
What is 2p
what is the "field" name that corresponds to 6 ligands being attached to a metal
Octahedral field
Rationalize why 40K will beta decay into 40Ca.
What is 40K has and odd number of neutrons (21) to an odd number of protons (19) and is not particualrly stable. This will beta decay to 40Ca which has a double magic number nucleus that is unusually stable.
Explain what a Combo Element is and give an example.
What is:
Def: A combo element can be defined as the combination of an (n-x) group ele- ment with an (n+x) group element to form compounds that parallel those of the (n) group element.
Ex. GaAs is a combo element for Ge
Tell me 5 things you know about Ca
What is:
1. Essential for life
2. Used in limestone
3. Used in cement
4. used in soda-lime glass
5. CaCO3 caves are made from acid rain
What is the phenomenon that causes the formation of D0 (delta naught)?
What is:
Orbital splitting due to the formation of tetrahedral and octahedral fields made created in the presence of ligands.
Name this compound: [CoCl4(NH3)2]−
What is * diamminetetrachlorocobalt(III)
Rationalize why Beryllium exhibits metallic properties even though it has a full 2s orbital
What is: The empty 2p band overlaps with the 2s band allowing the electrons to move throughout the metal structure
This allows elements lower on the periodic table to exhibit an oxidation state of n+2.
What is the inert pair effect?
Elements in a mostly pure state that can be found in a common household
What are Copper, Silver, Gold, Lead, Carbon, Silicon, and Aluminum?
This number tells us the shape of an atomic oribital
What is the magnetic quantum number (l)?
This type of isomerism allows metal complexes to have the same formula, but different chemical properties. Ex: Co(NH3)5BrSO4
What is Ionization Isomerism?
The reason Beryllium is a electrical conductor.
What is overlap of s and p orbital
Term for a molecule acting as an acid or a base
what is amphoteric
General formula of structure: (Bn Hn+4) or (Bn Hn+3)
What is nido
½(bonding electrons-antibonding electron)
What is bond order
Reason metals with d^0 configuration are intensely colored
What is charge transfer transitions
This type of magnetism is seen in common refrigerator magnets and when heated to extreme temperatures, will revert to a paramagnetic form.
What is a ferromagnet?
All of the alkaline earth metals form stable nitrides and one of the alkali metals does as well because it exhibits some covalent behavior.
What is Li3N?
This element has a +1 and +3 oxidation state, is a poor element, and is toxic because it mimics K+ ions.
What is Thallium?
According to Crystal Field Theory, these two orbitals will be higher in energy in an octahedral structure.
What are the dx2-y2 and dz2 orbitals?
[Ni(H2O)6]2+ is a complex that appears green in color and is known to absorb this color.
What is red?
