Title:- What are ionic compounds?
Introduction:-
Listen full article:
What are ionic compounds?is our main discussion today. I am just trying to focuss on the chemistry topic What are ionic compounds?which will be very helpful for class (ix) and class(x) school children, I think.
Explanation:-
To start this discussion, let us first know some basic definitions of chemistry
what are elements?
Answer:- The matters which are composed of only one type of particles are known as elements.e.g; Sodium (Na), Magnesium(Mg), Carbon(C).....
How elements are classified?
Answer:-Elements are classified in three types:-(i) Metals (ii) Non metals. (iii) Metalloids.
Metals:- Sodium(Na), Magnesium (Mg), Gold (Au).....
Non metals :-Carbon (C), Sulphur(S),Nitrogen (N)....
Metalloids :- Boron(B), Silicon(Si), Arsenic(As)....
What are molecules?
Answer:- When two or more than two similar or different types of atoms combine together chemically they form molecules
e.g;
H + H —----> H₂
Hydrogen molecule(Diatomic molecule)
Cl + Cl —-----> Cl₂
Chlorine molecule(Diatomic molecule)
H₂ + S —------> H₂S
Hydrogen sulphide(Triatomic molecule)
What are compounds?
Answer:- When two or more molecules or atoms chemically react themselves under some definite conditions and combines then they form compounds. e.g ;
C + ½ O₂ —---------> CO
(atom) (molecule) (Carbon monoxide is a gas/compound)
C + O₂ —--------> CO₂
(atom) (molecule) (Carbon dioxide is a gas/compound)
Finally I will discuss on todays topic
e.g ;
C + ½ O₂ —---------> CO
(atom) (molecule) (Carbon monoxide is a gas/compound)
C + O₂ —--------> CO₂
(atom) (molecule) (Carbon dioxide is a gas/compound)
Finally I will discuss on todays topic
What are ionic compounds?
Answer:- The compounds which are formed by the transfer electrons from metal atom to non metal atom are known as ionic compounds. e,g; Potassium Chloride (Kcl), Aluminium oxide (Al₂O₃)
Now we will learn a little more on ionic compounds .
How following ionic compounds are formed?
(a) Sodium Chloride (Nacl)
Answer:- Na is a metal, the electronic configuration of sodium (Na) = 2,8, 1 to complete octet and become stable sodium needs to collect 7 electrons from other element to full fill its outer most shell i.e its third shell or 'M' shell to get its nearest noble gas Argon (2,8,8) and to full fil octet and become stable or Na has to give up its only valence shell electron (1) to get 2,8 electronic configuration of Neon as sodium is a metal so according to metals chemical property , all metals give up electrons they do not accept electrons or they are unable to accept electrons due to strong inter molecular force, thats why sodium is also unable to accept 7 electrons.
Again, chlorine (Cl) is a non metal and its electronic configuration is 2,8,7 so to fulfil its octet chlorine needs to accept one(1)electron or must have to give up its valence shell's 7 electrons to get either its nearest noble 2,8,8(Argon) or 2,8 (Neon) gas configuration to become stable due to non metals chemical property non metals never give up electrons, so chlorin is also unable to give up electrons.So in chemical reaction between sodium(Na) and chlorine ,Sodium (Na) gives up its lone valence electron to get its nearest noble gas Neon's configuration(2,8) and become stable in the mean time chlorine accepts the lone electron which is given up by sodium(Na) to get its nearest noble gas Argon's (2,8,8)configuration and become stable and by the process of electrons transfer they form ionic compound (Nacl)
The formation can be given by:-

(b) Magnesium Oxide (MgO)
Answer:- Magnesium is a metal,the electronic configuration magnesium(Mg) is 2,8,2 and these electrons occupies s,p,and d orbits. To become stable or get its nearest noble gas ,argon's(Ar) configuration(2,8,8) magnesium need 6 more electrons to fill up its d-orbit and to become stable but due to inter molecular force of electronic attraction magnesium is unable to take 6 more electrons from other atoms.
On the other hand oxygen is a non metal and electronic configuration of oxygen is 2,6 ; which occupies its s and p orbits.To get its nearest noble gas, Neon's electronic configuration (2,8)oxygen need 2 more electrons to fill up its p-orbit and to get (2,8) neon gas configuration and to become stable.
So in the chemical reaction between magnesium and oxygen one magnesium(Mg) atom gives up its lone pair(2) electrons to get neons configuration(2,8) and become stable also produces Mg⁺² ion ,in the same time one oxygen atom accepts 2 electrons which are given up by magnesium (Mg) aton also to get its nearest noble gas neon gas configuration (2,8) and become stable also produces o²⁻ion. Due to electro atomic force of attraction between Mg⁺² ion and o²⁻ion they combines themselves and produces magnesium oxide (MgO)
The formation can be given by :-
Mg - 2e —-------> Mg⁺² (Magnesium ion)
(2,8,2) (2,8) neon gas
O + 2e —-------> O²⁻(Oxygen ion)
(2,6) (2,8) neon gas
Now
Mg⁺² + O²⁻ —------>Mg⁺²O²⁻ —->MgO
(magnesium oxide)
(c) Potassium Oxide (K₂O)
Answer:- Potassium is a metal,the electronic configuration magnesium(K) is 2,8,8,1 and these electrons occupies s,p, d and f orbit. To become stable or get its nearest noble gas ,krypton's(kr) configuration(2,8,8,18) potassium need 17 more electrons to fill up its f-orbit and to become stable but due to inter molecular force of electronic attraction magnesium is unable to take 17 more electrons from other atoms.
On the other hand oxygen is a non metal and electronic configuration of oxygen is 2,6 ; which occupies its s and p orbits.To get its nearest noble gas, Neon's electronic configuration (2,8)oxygen need 2 more electrons to fill up its s-orbit and to get (2,8) neon gas configuration and to become stable.
So in the chemical reaction between potassium and oxygen two potassium(K) atom gives up its lone (1) electron each to get argons configuration(2,8,8) and become stable also produces K⁺ ion ,in the same time one oxygen atom accepts 2 electrons which are given up by two potassium (K) aton also to get its nearest noble gas neon gas configuration (2,8) and become stable also produces o²⁻ion. Due to electro atomic force of attraction between 2K⁺ ion and o²⁻ion they combines themselves and produces potassium oxide (K₂O)

Conclusion:-
Ionic compounds are formed by the transfer of electrons from metal atom to non metal atom. So ionic compounds contain one metallic part........
