7.3 Discuss the trends in chemical reactivity of group 15 elements.
The element of group 15 :
React with hydrogen in order to form hydrides of type , where E = N, P, As, Sb, or Bi.
React with oxygen in order to form two types of oxides: where E = N, P, As, Sb, or Bi.
React with halogens in order to form two series of salts: and . Except because it lacks the d-orbital.
React with metals for forming binary compounds in which metals exhibit -3 oxidation states.
