Derive names for common types of inorganic compounds using a systematic approach

Nomenclature, a collection of rules for naming things, is important in science and in many other situations. This module describes an approach that is used to name simple ionic and molecular compounds, such as NaCl, CaCO3, and N2O4. The simplest of these are binary compounds, those containing only two elements, but we will also consider how to name ionic compounds containing polyatomic ions, and one specific, very important class of compounds known as acids (subsequent chapters in this text will focus on these compounds in great detail). We will limit our attention here to inorganic compounds, compounds that are composed principally of elements other than carbon, and will follow the nomenclature guidelines proposed by IUPAC. The rules for organic compounds, in which carbon is the principle element, will be treated in a later chapter on organic chemistry.

Ionic Compounds

To name an inorganic compound, we need to consider the answers to several questions. First, is the compound ionic or molecular? If the compound is ionic, does the metal form ions of only one type (fixed charge) or more than one type (variable charge)? Are the ions monatomic or polyatomic? If the compound is molecular, does it contain hydrogen? If so, does it also contain oxygen? From the answers we derive, we place the compound in an appropriate category and then name it accordingly.

Compounds Containing Only Monatomic Ions

The name of a binary compound containing monatomic ions consists of the name of the cation (the name of the metal) followed by the name of the anion (the name of the nonmetallic element with its ending replaced by the suffix –ide). Some examples are given in Table  3.5.2 .

Table  3.5.1 : Names of Some Ionic Compounds

NaCl, sodium chloride Na2O, sodium oxide

KBr, potassium bromide CdS, cadmium sulfide

CaI2, calcium iodide Mg3N2, magnesium nitride

CsF, cesium fluoride Ca3P2, calcium phosphide

LiCl, lithium chloride Al4C3, aluminum carbide

Compounds Containing Polyatomic Ions

Compounds containing polyatomic ions are named similarly to those containing only monatomic ions, except there is no need to change to an –ide ending, since the suffix is already present in the name of the anion. Examples are shown in Table  3.5.2 .

Table  3.5.2 : Names of Some Polyatomic Ionic Compounds

KC2H3O2, potassium acetate (NH4)Cl, ammonium chloride

NaHCO3, sodium bicarbonate CaSO4, calcium sulfate

Al2(CO3)3, aluminum carbonate Mg3(PO4)2, magnesium phosphate

NaOCl, sodium hypochlorite active ingredient in household bleach

CaCO3 calcium carbonate ingredient in antacids

Mg(OH)2, magnesium hydroxide ingredient in antacids

Al(OH)3, aluminum hydroxide ingredient in antacids

NaOH, sodium hydroxide lye; used as drain cleaner

K3PO4, potassium phosphate food additive (many purposes)

MgSO4, magnesium sulfate added to purified water

Na2HPO4, sodium hydrogen phosphate anti-caking agent; used in powdered products

Na2SO3, sodium sulfite preservative

Table  3.5.3 : Names of Some Transition Metal Ionic Compounds

Transition Metal Ionic Compound Name

FeCl3 iron(III) chloride

Hg2O mercury(I) oxide

HgO mercury(II) oxide

Cu3(PO4)2 copper(II) phosphate

Naming Ionic Compounds

Name the following ionic compounds, which contain a metal that can have more than one ionic charge:

Fe2S3

CuSe

GaN

CrCl3

Ti2(SO4)3

Solution

The anions in these compounds have a fixed negative charge (S2−, Se2− , N3−, Cl−, and  SO2−4 ), and the compounds must be neutral. Because the total number of positive charges in each compound must equal the total number of negative charges, the positive ions must be Fe3+, Cu2+, Ga3+, Cr4+, and Ti3+. These charges are used in the names of the metal ions:

iron(III) sulfide

copper(II) selenide

gallium(III) nitride

chromium(III) chloride

titanium(III) sulfate

Exercise  3.5.1  

Write the formulas of the following ionic compounds:

(a) chromium(III) phosphide

(b) mercury(II) sulfide

(c) manganese(II) phosphate

(d) copper(I) oxide

(e) chromium(VI) fluoride

Answer

(a) CrP; (b) HgS; (c) Mn3(PO4)2; (d) Cu2O; (e) CrF6

Answer 2

The given compound is francium sulfate.

Explanation:

While naming ionic compounds :

First, write the name of cation Then after that name of the anion.

Given

The molecule formula of a compound[tex]Fr_2SO_4[/tex]:

To find:

The name of the given compound formula

Solution:

Cation in formula = [tex]Fr^+[/tex] = Francium cation

Anion in the formula= [tex]SO_4^{-2}[/tex] = Sulfate anion

So, the name of the given compound is francium sulfate.

^Please help ASAP I’ll mark you as brainlister FILL in the blank

Answers

Highest energy level and S & P orbitals are found in valence electrons

The outmost free electron which is present in the outer shell is called valency. The number of elements joining together to form the compound also depends on the valency.

Each electron has revolved around the nucleus and that path is considered as orbit. The orbit is as follows:-

SPDF

The free electrons are usually lie in the outmost shell.

Hence according to the question, the correct option is S and P orbit.

Which pair of symbols represents nuclei with the same number of neutrons?
A. 56 Co and 580
B. 57Co and 58Ni
c. 57Fe and 58 Ni
D. 57Mn and 57Fe

Answers

Answer:

B

Explanation:

Mass number  = number of neutrons + number of protons

Atomic number is the number of protons in the nucleus.  

58Ni   : 58 is the number of neutrons + number of protons

atomic number of Ni is 28.  Thus,  58 -28 = 30 neutrons

57Co ;  57 is the number of neutrons + number of protons

number of Co is 27. Thus, 57 – 27  = 30 neutrons

2. Calculate the density of a rock that has a mass of 21.58 grams and causes the water in a
graduated cylinder to rise from 20.0yl to 25.4 ml.

Answers

Answer:

4.00 g/mL

Explanation:

Density is mass divided by volume (g/mL).

Mass of rock = 21.58

Volume of rock = 25.4 - 20.0 = 5.4mL

Density of rock = 21.58g / 5.4mL = 3.99629 g/mL

Round to the lowest number of significant figures which is three = 4.00 g/mL
