However, in group XIII (boron family), the electronegativity first decreases from boron to aluminium and then increases down the group. It is due to the fact that the atomic size increases as we move down the group, but at the same time the effective nuclear charge increases due to poor shielding of the inner d and f electrons.
Elements in the same group tend to show similar chemical characteristics. Vertical, horizontal and diagonal trends characterize the periodic table. Metallic character increases going down a group and from right to left across a period. Nonmetallic character increases going from the bottom left of the periodic table to the top right.
IWR technology matches handwritten or printed words to a user-defined dictionary, significantly reducing character errors encountered in typical character-based recognition engines. New technology on the market utilizes IWR, OCR , and ICR together, which opens many doors for the processing of documents, either constrained (hand printed or ...
The irreducible complex characters of a finite group form a character table which encodes much useful information about the group G in a concise form. Each row is labelled by an irreducible character and the entries in the row are the values of that character on any representative of the respective conjugacy class of G (because characters are class functions).
Reducing agents can be ranked by increasing strength by ranking their reduction potentials. Reducers donate electrons to (that is, "reduce") oxidizing agents, which are said to "be reduced by" the reducer. The reducing agent is stronger when it has a more negative reduction potential and weaker when it has a more positive reduction potential.

This series has the chemical formula X 2 H 6.Ethane is commonly found alongside methane in natural gas.The other hydrides of the chemical formula X 2 H 6 are less stable than the corresponding tetrahydrides XH 4, and they are more and more less stable as X goes from carbon (ethane C 2 H 6 is stable) down to lead (or flerovium) in the periodic table (diplumbane Pb 2 H 6 is unknown [1]).
