The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius.
Atoms must have equal  number of protons and electrons. To find  the number of neutrons you must find is  something called the mass number. Unfortunately,  the mass number isn't listed on the Table of  Elements. To find the mass number, all you need to  do is round the atomic weight to the nearest whole  number.he number of electrons in an element can change. For a neutral atom (net charge of zero), the number of protons is exactly equal to the number of electrons. So the number of electrons is also the same as the atomic number. However, it is possible to remove electrons and not change the identity of an element.
