First of all, please provide attention to the titles of your post. 'basics' makes no sense and I hope you will agree that the title I've updated makes more sense. Also, fix the CAPS LOCK key on your keyboard, it seems to be broken.

Current is a general characteristic of electricity, like voltage and resistance. It's a name given to the flow of electrons (charge) through a medium. Electricity is a generic name that's used for the common flow of energy to power all the electric stuff.

Current in general refers to any flow. Thermal currents, currents in a river and also electric currents.
Electricity deals with charges on ions, electrons and their movement.

Electricity is flow of power in the electrons state

Current in general is flow of power in any form

if electricity it is flow of electrons then what is thundering?

It's still the electrons.

yes Why are there no atoms in air ??

If atoms are present electrons are present

Well, they need not be free electrons but charged water particles (droplets) and air molecules. When the static charge exceeds the breakdown voltage between the source (clouds) and sink ground, another cloud or other there is a discharge. The violent discharge causes the air in the path to expand and rush away creating a vacuum. After the flash ends the air rushes back with a clap, which we call thunder.

thunder is a heavy and weighted electronic composition ,when it fall on the ground simply it creates drill like structure...its may be in many time bigger then magawatt power.................

Thunder is just the sound. It does not do any damage except to ear drums if too near.
Lightning can damage. It is a static discharge of mega proportions. It need not always strike the ground. More often it is between clouds carrying opposite charges. Lightning strikes the highest point on the ground which is tops of buildings and trees and such. Rarely it hits the ground. It does strike the ground if there are conducting minerals or metal ore.

Hello here thunder causes near vaccum state due to very high amount of charge passage in less time period this causes all the disturbances

Read bioSir's post that explains the effect more clearly

although the two terms might seem almost similar,they are not.Whereas electricity refers to the flow of energy in form of electrons,current refers to the flow of energy in any form from say thermal to electric.So,yeah...in as much as the defination of electricity can be substituted for current,,there is a slight difference

thundering refers to the sound produced when there is neutralisation of positive and negative ions within the atmosphere...so thunder can never be electrons whatsoever

thunder is simply a sound..lightining maybe..but that being weighted in electronic proportions,,,that is absurd

CEans the flow of charged ions can be also responsible for electric current , right ?

In case of lightning there are free electrons but also a majority of charged ions of air ,water ,etc.

But the current due to them is always less as the mobility is inhibited cos of their size

Charged ions charges similar to free electrons ( After all the birth of free electron and charged ion is a same incident ).
Now mobility ,off course its less in solids but what if its in gases(air in lightning ) and liquids (electrolytic process in batteries ) ?

Not real significance due to neighbouring atoms Can contribute very less current only

The static voltage must exceed the ionising voltage of air through the entire distance it has to travel from the sky to the surface of the earth Lightning occurs

It does not have a fixed value. It must be over 1kV

Electricity is a very general term used do describe current and voltage, the fields they produce, and other effects like induction, charge, capacitance, resistance...etc.Current is a term to describe the physical movement of electrons through a material.Voltage is energy. It is the force or charge applied to incite the movement of the electrons.

Anyway, you're not the only one with this question. This question has been asked before : https://www.crazyengineers.com/threads/difference-between-current-electricity.59410/ . I will merge the discussions later.

Basically there is no difference because, electricity is the flow of electrons and the flow of electrons is also called as current.

# But in some books, imbalance between electrons in an atom, which are ready to flow if we give them a path, is referred as Electricity(static electricity).

# And those electrons in a flowing manner is called as current.

Current is the part of a fluid that moves continuously in a certain direction while electricity is a property of amber and certain other substances to attract lightweight material when rubbed, or the cause of this property; now understood to be a form of energy (occurring in positive and negative modes) which is a fundamental property of electrons and certain other subatomic particles.

Electricity itself is a general term used to describe the electrical power provisioning. It's a general term used to define the presence of electric power that can be consumed by electric appliances and gadgets. 

Electric Current itself is an interesting entity. The general definition is that flow of electrons is called 'current'. A more accurate definition would be the rate of flow of negative charge through the conductor. Why 'negative', because electrons have the negative charge. 

The moment of electrons begins in one direction when potential difference is present at the two ends of a conductor.  This potential difference forces electrons to move; and we get electric current. 

The "Conventional Current Flow" is considered to be from the positive terminal to the negative terminal that is from the terminal at a higher potential to the terminal at lower potential.

The actual current flow, as you'd guess is the direction in which electrons are flowing - that is from lower potential terminal to the higher potential terminal.

Current: It is the "flow" of electrons from higher electric potential towards the lower. Its unit is ampere. ... Now individually these charges are enormous, but as the difference between the two is only 1 coulomb, its a very low difference in charge, so a little current will flow between them.
