A Net Ionic Equation is a chemical equation for a reaction which lists only those species participating in the reaction.
To write a Net Ionic Reaction, follow these 3 steps:
1) Start by simply writing the overall balanced chemical reaction. This is also called the Molecular Equation.
2) Then, you break apart the soluble molecules into the two ions that are formed (one positive and one negative). You will have to use the solubility rules to do this, they can be found online. If something is insoluble, it should not be broken apart. Write the reaction out with all of the separated ions. This is called the Total Ionic Equation.
3) Then, you simplify by canceling things out if they appear on both sides of the reaction, resulting in the Net Ionic Equation.
or write one reduction half
and other oxidation half and simply add them
For example, let look at the reaction of calcium carbonate with hydrochloric acid to form calcium chloride, water, and carbon dioxide:
--Molecular Equation:
CaCO3(s) + 2HCl(aq) ---> CaCl2(aq) + H2O(l) + CO2(g)
--Total Ionic Equation:
CaCO3(s) + 2H+(aq) + 2Cl-(aq) ---> Ca2+(aq) + 2Cl-(aq) + H2O(l) + CO2(g)
--Net Ionic Equation:
CaCO3(s) + 2H+(aq) ---> Ca2+(aq) + H2O(l) + CO2(g)
Notice that the Cl- was canceled out from the Net Ionic Equation, because it really isn't playing an important part of this reaction. It is just there to balance out the charge because you can't have an ion just by itself -- you must always pair an ion with another one of opposite charge so that the overall charge is zero.
it must be cleared that while writing a chemical equation... it must be in symbols of that element
then the numbers of the atoms used in the reaction must be equated to both the sides that is it must be equal to right hand side as well as left hand side... we need to remember the symbols of that element
By removing from the complete equation any ions that occur in the same number on both sides of the complete equation.

Yes. If both compounds are insoluable in water then the complete/overall ionic equation and the net ionic equation will look the same. The only way they look different is if there are spectator ions(ions that appear on both sides of the equation).
The net ionic equation has only the species involved in the chemical reaction.
The net ionic equation that describes the reaction when these solutions are mixed is the net summation. This is the net ionic equation for the chemical reaction.

All elements are disassociated so there is no net Ionic equation
The total ionic equation shows all of the equation, even the spectator ions. The net ionic equation shows the net change after spectator ions have been removed.
