Without going into the detailed mathematical proof (cos it's unnecessary), the energies of electrons can only have certain specific values. If you imagine a staircase, the steps are set at certain specific heights. There are no in between steps between steps. Let these steps represent different energy levels, with the energy increasing in value as you move up from one step to the next. Well, a comparable situation exists in an atom. There are certain discrete "steps" or energy levels in an atom, and an electron can only exist at one of these levels. It cannot exist anywhere in between any of the levels. So, an electron can only have certain amounts of energy. If you stimulated an electron with some extra energy, such as an electrical charge, the electron would only be able to absorb a certain amount, or quantity, of this extra energy, and this quantity would correspond to the difference in energy between one energy level and another (although these energy levels need not be adjacent - "steps" can be missed out when the elctron jumps levels). On the atomic scale, these quantities of energy are given the name "quanta." In friendlier terms, they are called packets of energy. These packages can only come in certain defined sizes.

It means that energy can't have just any old number. It can only have certain numbers
that are spaced by a constant amount, but nothing in between those. When energy moves
from one place to another, it has to move in those quantities, and it can't move in fractions
of them.
An example that may help:
Money is quantized. The price of something for sale can't be just any old number.
It can only have numbers that are 1 penny apart, but nothing in between pennies.
You can talk about prices that are between pennies, but once you transfer money
from one person to another, it can only move in multiples of pennies, not in fractions
of them.
It means that it is at a certain energy level, and there are no in between values. So, it can be 1, 2, 3, 4, etc, but cannot be 2.3 or 3.5, etc. The electrons have certain energies and they are like packets, and they don't exist in fractions of packets.
Electric charge comes in multiples of an electron , 1.6E-19 Coulombs.
When a quantity is "quantized," it means that the quantity exists in discrete indivisible units. For example, the magnitude of electric charge is quantized, and the quantum of electric charge is the charge of the electron e. There is no known free particle with a charge of 1/2 e or 9.1254e, only particles with charges of 1e, 2e, 5e, 99e, 423425e, etc.There are numerous other quantities that can be quantized including angular momentum, energy, and even electrical conductance.
In physics, when a quantity is "quantized," it means that it can be broken down into indivisible units.Imagine a tower built out of Legos. If you break down that tower, you will find it's made out of 2×4 blocks, which cannot be broken down any further. We say that the tower is quantized, and the quantum unit of the tower is a 2×4 block.Charge is quantized because all charges are made up of a "building block" of charge. The quantum unit of charge is 1.602 × 10^-19 Coulombs, or 1 e, the charge of an electron/proton.In nuclear physics, electrons and protons are made up of quarks which have charges of -1/3 e or +2/3 e, so they are truly (at this point), the quantum of charge.
electrostatic shielding is the method of protecting a certain region of space or any sensitive instrument from the influence of the external field produced by an electric charge
As far as we know there isn't one. Electric charge is an intrinsic part of certain subatomic particles. We don't know why, nor do we know why they have the characteristic magnitude they do ... it's just how the universe is. Up quarks (which have a charge 2/3 as large as the charge on an electron, but of opposite polarity) and down quarks (which have a charge 1/3 as large as the charge on an electron, and of the same polarity) combine in such a way that protons wind up having the same charge as electrons but opposite polarity. We don't know why this should be so, but it's very convenient.If you meant the gauge particle ... the gauge particle for the electromagnetic force is the photon (which is not, itself, charged).There is no specific substance for electric charge. Lots of subatomic particles - but not all of them - have the property of electric charge, which may be positive or negative (or neutral). In practice, electric charge is often carried by electrons, but it may also be carried by positive or negative ions, by positive holes, etc.

One particle can turn into another particle or several other particles (particles decay, for example, much like radioactive nuclei) but electric charge is neither created nor destroyed, so no matter what happens to subatomic particles, the end result will have exactly the same amount of electric charge as there was originally. This principle is officially known as conservation of electric charge.
ELECTRIC FIELD The electric of a charge is the region of space surrounding in which a point charge can experience its influence in the form of a force The regon around any charged body in which coloumb's force is experienced by some other charged body is called "electric field" of the first body.

electrostatic shielding is the method of protecting a certain region of space or any sensitive instrument from the influence of the external field produced by an electric charge
What is meant by polarity? Answer An electric charge has a polarity of either positive or negative. Also a voltage has a polarity, in that it could be positive or negative, with respect to some other voltage, such as the one at the other end of a battery or electric circuit.

The past opposite of meant would be meant as in if you were saying " 5 years ago I meant to go to Africa.". And the future would be mean to as if in saying " I'll say I mean to do that."
