(a)
Interpretation:
Formula of sodium selenide has to be written.
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 nickel(II) bromide has to be written.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
Formula of dinitrogen pentoxide has to be written.
Concept Introduction:
Two or more nonmetals combine to form molecular compounds. The naming of molecular compound is given by following two rules.
- Element that is present in far left of the periodic table appears in the name first.
- Element that is closer to bottom within any of the group appears in the name first.
Numerical prefixes are used in case of molecular compounds to mention how many times the atom of same elements occurs in the formula. Prefix mono is not used for the first element while for the second element it is used.
From the name of molecular compound, the molecular formula can be obtained by considering the name of the first element and second element along with the prefix. The prefix represents the number of atoms of same element is present in the molecular formula. This prefix is entered in subscript in molecular formula after the
(d)
Interpretation:
Formula of copper(II) sulfate has to be written.
Concept Introduction:
Refer part (a).
(e)
Interpretation:
Formula of ammonium sulfite has to be written.
Concept Introduction:
Refer part (c).
