Atomic radius, half the distance between the nuclei of identical neighbouring atoms in the solid form of an element. An atom has no rigid spherical boundary, but it may be thought of as a tiny, dense positive nucleus surrounded by a diffuse negative clou
Atomic Size & Atomic Radius - Atomic Size is the distance between the center of the nucleus and the outermost shell of electrons is called the atomic radius. Atomic radii can be measured by measuring the distance between the nuclei of atoms in a metal. T

Many references give table of atomic radii. Sometimes in text books and other sources, the rather vague term "atomic radius" is not defined and in such cases it is therefore not clear what the values actually mean. The values given here for atomic radius are calculated values using methods ...
1.1 Particles in the atom and atomic radius 1 understand that atoms are mostly empty space surrounding a very small, densenucleusthat contains protons and neutrons; electrons are found in shells in the empty space around the nucleus 2 identify and describeprotons, neutrons and electrons in terms ...
