atomic radius
Electron shielding decreases the effective nuclear charge.
As you go down the first group (or any group), you are adding protons and electrons. As you add more and more protons, the effective nuclear charge will increase.

central forces are one which act centre to centre between two particles and are inversely proportional to the square of the distance between them. nuclear forces violate this relation so they are non central in nature.

The atomic radius decreases along a period. It is because of increasing effective nuclear charge along a period.
We are familiar with forces, such as the force of gravity and the electromagnetic force, which are inversely proportional to the square of the distance between the center of the objects which are interacting by means of that force, however, not all forces are like that. The strong nuclear force is much more dependent upon distance. It is inversely proportion to the sixth power of the distance, not the square. So it goes in a very short distance from being a tremendously strong force, to a completely negligible force.
Yes, nuclear fission reactors are very effective and can generate a lot of power. That is why nuclear fission reactors are very effecive
Yes they are very effective. Nuclear weapons are dangerous and really effective to destroy all life on earth. They are very powerful.
This will vary widely and be proportional to yield.
Atomic radii decreases on moving from left to right as the effective nuclear charge increases.
The periodic table organizes the elements by atomic number (number of nuclear protons).
moving from left to right across a period, one electron is added for each element.example: Boron has 3, Carbon has 4.
the effective nuclear charge on barium is 2.
