The atomic radius of elements in the periodic table in easy way​ by measuring the distance between the nuclei of two touching atoms.

Explanation:

• The atomic radius can be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance will give the atomic radius.
• The same atom could have a different radius depending on what is  around it.
• The  trend of atomic sizes,it increases as one moves downwards in the groups in the Periodic Table of the Elements. Here the number of energy levels increases and thus greater the distance between the nucleus and the outer most orbital.
• Here the electrons fill the outer electron shells. Atomic radii will decrease as we move from left to right in the Periodic Table.
• It is the distance from  the nucleus center to the outermost shell of an electron.
• it is also the measure of the size of its atom.

The general trend is that atomic sizes increase as one moves downwards in the Periodic Table of the Elements, as electrons fill outer electron shells. Atomic radii decrease as one moves from left to right across the Periodic Table.
