Is types of bonds and formation and naming of ionic compounds the most trending thing now?





Chemical bonding:
Definition: .
When  two or more than two elements combine to form a new  compounds an interaction of  chemical bond grips the atoms together.
Types of chemical bonds:


There are two main types of chemical bonds achievable in compounds, ionic bonds and covalent bonds. Both type of  these bond includes a rearrangement of electrons between the bonded atoms.
Metallic bonds:
In addition metallic bonds suggest itself with a pure metal.
Formation of ions and ionic bonds.
By recalling the concept of chemical bonding we can say that ionic compounds are formed by loosing electrons from one atom and gainig in another atom of an element like metals .Their outer most shell of  electrons  can be made visible for identification to the other nearest element especially noble gases. This is a strongly fruit full and suitable condition which is liable to minimize the phenomena of reactivity of noble gases. When  two or more than two atoms gain or lose electrons to reach  at the same electron arrangement like as the noble gas, than we can say that they are isoelectronic with the noble gas.

Ionization energy:


On the other hand, the production of metal cations from metal atoms needs energy which is called its  ionization energy.
In this procedure, some of the atoms require a positive electric charge which is  equal in magnitude of the removed electrons and after this process they are known as cations. After the removal of required number of electrons than the resulting cation is isoelectronic to a noble gas. A lot of energy is required for the removal of second electron so this phenomena does not exists here . So only a small amount of energy is needed here for the following phenomena
Na atoms can form Na+ cations:
Na+ cation can also formed by Na atoms  in this state they are isoelectronic with a  noble gas neon, but sodium cannot form Na2+ or Na3+ cations because the large amount of energy is needed in this process. With some omissions, in the process for  becoming isoelectronic with a noble gas, more than three electrons cannot  be removed from an atom in the formation of cations because the amount of ionization energy is needed in large amount and the formation of  large positive charge would result in an unstable cation. For the formation compounds that will need the transfer of more than 3 electrons between reacting atoms, a special type of  bonding  covalent bonding  is usually used.
Non-metals:
Elements of some other groups like non-metals can acquire with energetic form this state by their atoms achieving enough electrons to obtain the same arrangement  of the electrons as their noble gas have which is near to them . In this procedure these elements get a negative charge and are called anions.
How are ionic compounds named?
Compounds of two elements  which are totally different from each otjher and they further cannot be simplified by any chemical means from each other are known as  ionic compounds.
Rules for naming ionic compounds:
Rules for naming ionic compounds are very simple and easy given  as follows:
The compound is named in two separate words, the cation being named first and the anion last.
The cation name remains unchanged as the element but where necessary with the charge affixed in brackets as Roman numerals.
 Anions  which are formed from an element take the stem from the name of the element and at  the end "ide" is attached e.g. oxide from oxygen. No special word is  needed  for ending of the cation as it is clear that a compound is being named when two words are used in the name. Lower case letters are used for the name, together with the first letter.

Examples:
The subsequent examples demonstrate the correct naming of ionic compounds. NaCl sodium chloride (contains Na + and Cl – ions)
KI potassium iodide (contains K + and I – ions)
CaF2 calcium fluoride (contains Ca 2+ and F – ions)
Rb2O rubidium oxide (contains Rb + and O 2– ions)
BaS barium sulfide (contains
Ba 2+ and S 2– ions)
Mg3N2 magnesium nitride (contains Mg 2+ and N 3– ions)
CuCl2 copper(II) chloride (contains Cu 2+ and Cl – ions)
SnS tin(II) sulfide (contains Sn 2+ and S 2– ions)
Fe2O3 iron(III) oxide (contains Fe 3+ and O 2– ions)
AuCl3 gold(III) chloride (contains Au 3+ and Cl – ions)
