An electron is much larger than an atom?
an electron is much much smaller than an atom. An electron is a portion of the nucleus in an atom.
Why don't scientists define the atomic radius as the radius of its electron cloud?
An electron cloud does not have a specific radius -- it is in fact a probability distribution. An analogy is the atmosphere. What is the radius of the atmosphere? You can't give one number because there is no dividing line where the atmosphere exist on one side but doesn't on the other. Instead, it just gets thinner and thinner and thinner... (see the Related Questions to the left for more about the sky). You can meaningfully talk about a radius that includes a percentage of the total. For instance, you can say that at some radius, you will find the electron inside that radius 95% percent of the time. But if you picked the radius where it would be 99% of the time inside, it would be much larger. To have the percentage be exactly 100%, the radius would be infinite! Because of this complication, atomic radii are usually determined by the distance between to atoms when they are in a bond together -- and is taken to be approximately half the distance between the two nuclei (although it is slightly more complicated than that in fact).
Why electron microscope is called as electron microscope?
The resolution of electron microscope is much higher than that of light microscope, allowed detailed ultra-structural examination. That's why electron microscope is called so.
Is the electorn the biggest part of an atom?
The electron is actually the smallest particle. The neutron is the largest particle, followed closely by the proton. The electron is much, much smaller.
Does potassium or krypton have bigger atoms?
If by "bigger" you mean having more protons, then Krypton has more, and therefore is heavier, weighing in at 83.8 (atomic weight). Potassium weighs a mere 39.0983. However, if by "bigger" you mean how much space it takes up, the atomic radius of Potassium is 227 pm, as opposed to Krypton's radius of 88 pm. The atomic radius is the average distance from the nucleus to the outside boundary of the electron cloud. I'd go to the internet for more, but hope this helps anyway.
Compared to a proton an electron has?
The same quantity of a charge and the opposite sign.
How much energy is released by the atom when an electron moves from n 3 to n 2?
182 kJ
What is going to happen to the size of a positive ion as compared to the original atom?
The positive ion has donated an electron to another atom making the other atom a negative ion and much larger in radius. The positive ion is now much smaller in radius.
Why doesn't the electron lose twice as much energy when it moves in two levels as it loses when it moves only one energy level?
The energy gaps between levels are not all the same.
Why would an increase in atomic radius make it easier to lose an outer electron?
It's because as atomic radius increases, so do the number of electron shells. The full electron shells closer to the nucleus act like a barrier or shield that reduces the pulling force exerted by the Nucleus on the outer electron. Since the nucleus's pulling force is reduced, an electron on the outer shell can escape much more easily.
How can atomic radius affect the interactions between two elements or atoms?
the atomic radius doesn't mean much in how an atom interacts with another. The valence shell (outer most electron orbit) dictates whether or not atoms will form compounds

What happens if the ball moves at address?
nothing much the points might change but it isn't very crucial
How much is radius squared?
It depends on the value of the radius.

Why does the rate of change of the radius of a balloon slow down as the balloon gets bigger?
The volume of a balloon is like that of a sphere. So we use 4/3x Pix radius3 .Now plug in some numbers for V and see how radius changes. You will see if you go from a small volume to one a little larger, say .1 to .15, there is a pretty big change in the radius. Now try 1000 to 1000.15. You will see the change in the radius is much smaller.That is because of the fact the radius is cubed. I can't draw it here, but have a look at the graph of x cubed and that may shed some light on it.
How much longer is the diameter form the radius?
The diameter is twice as large as the radius.
