Question of the day?

Apparently a four year old asks 450 questions a day. How many questions am I short, and from where in Citizendium can I find the answers?

Hallowe'en is coming up. What is the origins of this tradition? How is it celebrated? How many 'spooky' tangents can I come up with from this topic? 

* All Souls' Day ; Día de los Muertos (I guess this would be Day of the Dead in English?_ ; other traditions that commemorate the dead?
* All right, and as the day has lost a bit of its spiritual signicance for costumes and candy, and how can one ignore the lore and history regarding the seance, ouija boards, and the cultural background behind the legend of the vampire?

triboluminescence: Oct 24's 'what the...? that is so cool and weird' question of the day

When I blow out a candle in the living room, how does this activate the smoke detector in the foyer? How come the smoke detector can't tell if I've overburned the ginger on the oven (though it might have been the rangehood)?

If 'you are what you eat', does that mean I want to be an acai berry when I grow up? (no, not a 'serious' question, that was just an excuse to create redlinks)

Eight-tracks, records, and cassettes are now niche markets, or rather former audio recording staples of the past. How did they work? How does a digital recorder, that transfers them to something like a CD or a DVD, work? What other portable data storage items (? what's the word for that?) existed out there?

Where'd my references about the organic growth of medieval cities nick off to?

Colour in transition metals

Transition metal complexes are usually coloured. The colour results from absorption of photons in the visible region of light.

Substances that appear black absorb all wavelengths of light in the visible spectrum. Those that appear white reflect all wavelengths. Substances that appear colourless absorb light in the infrared or ultraviolet regions of the light spectrum, therefore do not appear coloured to the human eye. All cations, anions and oxoanions of the representative elements are colourless.

This can be explained by the octahedral geometry of complex ions, and by the location of atomic orbitals in the d shell.

(diagram needed - complex ion with d orbitals between the axes)

(animation - seems to capture idea best - electron approaching d orbitals, splitting energy between orbitals closer to the ligands and those further away)

Transition metals that are coloured are those who have partially filled d orbitals. Colourless complexes of transition metals are those which have no d electrons present, for example Sc3+, or when all d orbitals are filled. It is only partially filled d orbitals that result in colour because there is space for an electron to be promoted from the lower energy d orbitals to the higher energy d orbitals.


An example of colours produced by some transition complexes is below.


Table: Colours of the hydrated complex ions of the first transition series.[3] (Note to self - [| this how one makes a table]

Colour Ions and number of 3d electrons
Colourless Sc3+ (0) Cu+ (10) Zn2+ (10)
Red Co2+ (7) Mn2+ (5)
Green Fe2+ (6) Ni2+ (8) V3+ (2) Cr3+ (3)
Purple Ti3+ (1)
Violet V2+ (3) Cr3+ (3) Mn3+ (4) Fe3+ (5)
Blue Cr2+ (4) Co3+ (6) Cu2+ (9)
Yellow [FeCl]2+ (5)


The energy difference Δ is called the crystal-field splitting energy.

ΔE = hv = hc/λ = splitting energy = Δ

Within transition metals Δ is often in the range found in the frequencies of visible light. This means that an electron can be excited from one of the lower-energy d orbitals to a higher energy d orbital by visible light.

Complementary colours - definition

Complementary colours are two colours that combine to produce white light. Therefore if a substance only absorbs a wavelength, it will reflect the wavelength of the complementary colour and appear that colour to the eyes. For example, permanganate appears purple because it absorbs green light.

Absorbed wavelength in nm (colour) Observed colour
400 (violet) Greenish yellow
450 (blue) Yellow
490 (blue-green) Red
570 (yellow-green) Violet
580 (yellow) Dark blue
600 (orange) Blue
650 (red) Green


The presence of transition metals in gemstones results in the varied colours of gems.

Crystal-field splitting theory

Crystal-field theory is a theory of chemical bonding, first explored by physicists in the early 1930s in relation to the spectra of ionic crystals.

A limitation of crystal-field theory is that it cannot explain the colour spectrum of complex ions or the splitting order of all ligands.

Applications

Wavelength absorption and emission by atoms is used in spectroscopy to identify elements.
