Concept explainers
(a)
Interpretation:
Formula of calcium nitride has to be given.
Concept Introduction:
Naming of ionic compounds that contain monoatomic ions are given by using the name of the cation (mostly metal), which is followed by the name of anion. The anion (mostly nonmetal) is named by adding the suffix “-ide”. When an ionic compound is made up of only two elements, it is known as binary compounds. In case of binary compounds, the numerical prefixes are not shown in the name because the number of ions is inferred from the empirical formula.
In order to obtain the formula from the given name, the cation and anion are identified first. Then the symbol of the cations and anions are written using the charge. Number of subscripts are added either to cation or anion in order to balance the charge.
(b)
Interpretation:
Formula of chromium(III) perchlorate has to be given.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
Formula of tin(II) fluoride has to be given.
