Group-II elements react with water evolving hydrogen. This reactivity increases down the group from Be to Ba. They displace hydrogen from acids except Be with oxygen Be, Mg and Ca form monoxides while Sr, Ba and Ra form peroxides on heating with hydrogen, they form metal hydrides except Be with carbon, they form carbides on heating such as acetylides, methanides and allylides. When heated with halogens they form halides having different properties. Ionic hydride is not formed by

Dihydrogen, under certain reaction conditions, combines with almost all elements, except noble gases, to form binary compounds, called hydrides. If 'E' is the symbol of an element, then hydride can be expressed as EH_x (e.g.HgH_2) or E H_x (e.g. B_2H_6) . The hydrides are classified into three categories : ionic, covalent and metalic Which of the following is not an example of Ionic hydrides

Read the following passage and answer the questions that follow. Electron-precise compounds have the required number of electrons to write their conventional Lewis structures. All elements of group 14 form such compounds which are tetrahedral in geometry. Electron - rich hydrides have excess of electrons which are present as lone pairs. Elements of groups 15-17 form such compounds. Metallic hydrides are formed by many d-block and f-block elements. These hydrides conduct heat and electricity though not as efficiently as their parent metals do. They are non-stoichiometric. A non-stoichiometric hydride is formed by
