Question

One half of the distance between the-of two covalently bonded atoms of the same elements in a molecule is called as Covalent radius.
a Electrons
b inner energy levels
c Nuclei
d All of these ​

Answer 1

Answer:

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 shells of electrons. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Four widely used definitions of atomic radius are: Van der Waals radius, ionic radius, metallic radius and covalent radius. Typically, because of the difficulty to isolate atoms in order to measure their radii separately, atomic radius is measured in a chemically bonded state; however theoretical calculations are of course simpler when considering atoms in isolation. The dependencies on environment, probe, and state lead to a multiplicity of definitions.
