How to get Atomic Radius?
The radius of atom can be measured by the finding distance between the nuclei of two touching atoms then dividing it by 2. Atomic radius is also measured by calculating the distance between the center of the nucleus of an atom and its outermost shell. Atomic radius is measured in order of 10-12 to 10-15 meter. Since, as per quantum mechanical model the electron around atom is in the form of cloud, hence its doesn’t have defined boundary. In such case, the atomic radius is calculated by dividing the distance between two successive nucleus by 2.
The calculation of atomic radius is a complicated process because electron form cloud shell outside nucleus and does not have any fixed shape. The electron in an atom experiences repulsive and attractive force which make it more difficult to precisely calculate the atomic radius and thus atomic size of an atom. However, Bohr attempted and gave formula for single electron system of atom to precisely calculate its radius. This formula can be used to get an idea of radius in multi electron atom. Let’s learn the atomic radius formula
Atomic Radius
Atomic Radius is defined as the total distance between the center of the atom to the outermost orbit in which the electron is revolving. Atomic Radius tells about the atomic size. Since Atoms are considered to be spherical, the size of an atom can be calculated by measuring its radius. Atomic radius is necessary to understand the behavior and properties shown by atoms. Some of the properties of an atom are affected by atomic radius.
