After the rules of IUPAC (NAMING OF NEW ELEMENTS - IUPAC Recommendations 2002) new elements must have a three letters symbol and the suffix -ium at the end of the name; for these letters the meaning is:
- un is one derived fro the Latin unum
- nil is zero
- the third letter is derived each from a Latin numeral
Example: the element 115 - ununpentium
Now the Periodic Table has 4 elements with this type of symbols and names: Uut, Uup, Uus, Uuo.
These names remain in use until the discovery of this element is generally recognized and validated by IUPAC. After this an element receive a "normal" name, which also must be approved by IUPAC.
Not all periodic tables have a different color for these elements.

How are the properties of iron sulphide different to the properties of the elements iron and sulfur?

Which elements are responsible for the different colors of hair of different people?
Colours of the hair of different people differ due to presence of transition elements in them. Brown colour of hair is due to the presence of compounds of iron (Fe), cobalt (Co) and copper (Cu), whereas molybdenum (Mo) compounds impart red colour and titanium compounds give ginger colour to the hair.

What property is not a periodic function?
Colour is a property that is not a periodic function.
Why do different elements emit different colors when they are heated?
because when elements are heated there electrons become excited and jump through the elements "steps" and as they become less excited the jump back down steps emitting a unique wavelength and the visible wavelength is the colour we see -------------------------------------- The wavelength of the spectral lines emitted by different elements are specific for each element. Consequently the colour is also different.

Can scientists analize the elements of a star?
Scientists can assess which elements are present in the star, by looking at the light it gives off and breaking this light down into the different colours that make up the total colour. They look at the spectrum given off. The different elements present in the star cause different light wavelengths (or colours) to be emitted.
