Nuclear fusion in the sun involves hydrogen (h) atoms combining to form helium (he). a student claims that since the atmosphere contains hydrogen, any fusion reaction on earth would result in an uncontrolled chain reaction. what is wrong with the student's reasoning? the hydrogen in air is not densely packed enough for an uncontrolled chain reaction. uncontrolled chain reactions can only happen during nuclear fission. it is impossible to cause a fusion reaction to happen anywhere outside of the sun. we are safe because there is no radioactive hydrogen in the air.

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
