  Encyclopedia: Period 1 element
A Group 4 element is an element in periodic table group 4 (IUPAC style) in the periodic table, which consists of: titanium (22) zirconium (40) hafnium (72) rutherfordium (104) All of these elements are classed in Group 4 because their valence shell holds four electrons.
A Group 5 element is an element in periodic table group 5 (IUPAC style) in the periodic table, which consists of: vanadium (23) niobium (41) tantalum (73) dubnium (105) All of these elements are classed in Group 5 because their valence shell holds four electrons.
A period 3 element is one of the chemical elements in the third row (or period) of the periodic table of the elements.

 Trends Across Period 2 of the Periodic Table
As one moves from one element to another on the right, one more proton is found in the nucleus, and one more electron is found in the same electron 'shell' (energy level).
For this reason, all the elements in Period 2 have the first electron 'shell' (energy level) filled with 2 electrons (the electronic configuration of Helium).
As we move from left to right across the period one more proton is added to the nucleus of each successive atom, and one more electron is added to the same electron 'shell' (energy level) of each successive atom.

The Coverage element describes the spatial and temporal characteristics of the object or resource and is the key element for supporting spatial or temporal range searching on document-like objects that are georeferenced or time-referenced.
This element may be used in describing resources from many different fields, e.g., archaeology, art, cartography, geography, geographic information systems, medicine, natural sciences, etc. - any field that deals with georeferenced information, spatial data, or time-referenced data.
The values may be: a longitude/latitude pair (for a point); a set of four longitude/latitude values for a bounding box (in the order westernmost longitude, easternmost longitude, northernmost latitude, southernmost latitude); or a set of n longitude/latitude values for any polygon or for a line.

When the PSO levy was established, it was agreed that, for the sake of consistency, it would be subject to the same indexation arrangements as other excises (ie indexation twice a year in line with movements in the Consumer Price Index).
