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.

In this article, we are going to learn about atomic radius, types of atomic radius, the atomic radius chart of some common elements, trend of atomic radius in the periodic table in detail.

Atomic Radius Definition

Atomic radius of an atom is defined as the total distance from nucleus of atom to the outermost orbit in which electron is revolving....

Atomic Radius Meaning

Atomic Radius is the distance between the center of the atom to the outermost shell of the atom. Atoms are made up of three subatomic particles namely – electron, proton, and neutron. Protons and Neutrons are present in the center of the atom inside the nucleus. Nucleus is present in the center of the atom. Proton tightly bounded together. Electrons revolve around the nucleus in a defined circular path known as orbit. The overall structure of an atom is assumed to be in circular shape. Atomic radius is generally measured in Picometer. Atomic Radius gives the idea about the atomic size. Atomic Radius is measured in the power of 10-9 to 10-12. The plural form of Atomic Radius is Atomic Radii....

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....

Atomic Radius Formula

Atomic radius of any element is inversely proportional to its Atomic Number. Because , as atomic number increases effective nuclear charge increases which reduces the size of atom. The formula for Atomic radius of any element is given by :...

Atomic Radius vs Ionic Radius

Atomic Radius and Ionic Radius are two most common terms used for determining the atomic size. The term atomic radius signifies the size of an atom in its ground state while the term ionic radius signifies the size of an atom after it has lost or gained electron i.e. in its ionic state. The basic difference between Atomic and Ironic Radius is tabulated below:...
