Concept explainers
(a)
Interpretation: Formula of name of compound (rubidium hydroxide) should be written.
Concept Introduction: The formula of compound identifies the atoms or ions present in it. The formula is formed by crisscross method, in which, charge on one ion goes to subscript of other and vice versa. In a compound, generally ion with positive charge is written same as the name of element for but ion with negative charge is written with suffix −ide. For example the name of NaOH is sodium hydroxide. Where, sodium is Na+ ion and chloride is Cl- ion.
(b)
