IONIZATION ENERGY

IONIZATION ENERGY:-

   The minimum energy required to remove an electron from its gaseous atom to form an ion is called ionization energy and the process is called ionization. For example

ATOMIC SIZES

ATOMIC SIZES:-

    Size of an atom is very important in determining its properties whether physical or chemical properties. Atoms are assumed to be spherical so radii is used to determine there sizes. There are various radii to determine size of an atom depending upon type of compound.

Balancing Chemical Equations Easy Algebraic Method

CHEMICAL BOND

CHEMICAL BOND:-

Force which hold together two or more than two or more than two atoms or ions to form a large variety of compounds is known as chemical bond. These forces are responsible for the bonding and shape of molecules as shown in fig 

CHARGING AND DISCHARGING OF A CAPACITOR

CHARGING AND DISCHARGING OF A CAPACITOR:-

Capacitor never charges or discharges alone but at least one resistance is attached with it.

Its charging and discharging behaviours both are not linear (straight line) but it is exponential (curved).

How long a capacitor will take in order to charge or discharge depends on product RC of circuit known as time constant that is the product of resistance (R) and capacitance (C) is constant which is time constant.

ENERGY STORED IN CAPACITOR

ENERGY STORED IN CAPACITOR:-

     We know that capacitor is charge storing device. Its charge storing ability that is capacitance increases in the presence of dielectric medium as explained in the previous topic. Capacitor store its energy inside electric field which can be calculated as follow:                                          

We know that Potential Difference=  Work

                                                     Charge

Or V = Energy

           Charge   

Or Energy = V.Q ----------(i)
