The oxidation state of elements in the p-block is maximum when it is equal to a total number of valence electrons i.e. the sum of S and P electrons. One of the most interesting facts about the p-block elements is that it has both non-metals and metalloids. The first member of the p block elements differs with other elements in two major respects: Hydrides of p-Block Elements Definition of hydrides Hydrides is defined as the compounds formed when elements react with hydrogen to form the compounds. For example - N H 3, C H 4, N a H, B 2 H 6 etc In general it can be represented as M + H 2 g → hydride compound Note: Some hydrides may not be produced directly from the reaction of hydrogen with the element but can be produced by some other indirect methods. For example, Diborane is prepared from the reaction of sodium borohydride and ... p-Block elements are those in which the last electron enters the p-orbital of the valence shell. They are placed in Groups 13 to 18 of the modern periodic table.
