Atomic Radius Trend
Atomic Radius of Element in periodic table vary in a systematic manner across the groups and periods. Let’s learn the Priodic variation of Atomic Radius in detail.
Atomic Radius Across Group
Atomic radius increases as we move from top to bottom in a group because number of shells increases due to increase in number of electrons. As the number of shells increases the size of atom also increases.
Atomic Radius Across Period
Atomic radius decreases as we move from left to right in a period due to increase in effective nuclear charge (The nuclear charge is the total charge in the nucleus of all the protons). As the number of protons increases, nuclear charge increases which shrink the size of atom.
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.
