1) Covalent Radius. Covalent radius is one half the distance between the nuclei of two covalently bonded atoms of the same element in a molecule. Therefore, r covalent = ½ (internuclear distance between two bonded atoms). The internuclear distance between two bonded atoms is called the bond length. Therefore,
Formula of the Radius of Curvature. Normally the formula of curvature is as: R = 1 / K’. Here K is the curvature. Also, at a given point R is the radius of the osculating circle (An imaginary circle that we draw to know the radius of curvature). Besides, we can sometimes use symbol ρ (rho) in place of R for the denotation of a radius of ...
The radius of gyration or gyradius of a body is always about an axis of rotation. It is characterized as the spiral distance to a point which would have a moment of inertia. The radius of gyration is a geometric property of a rigid body. For example, the centre of mass. It is equivalent to the body’s real dissemination of mass.
Write its physical significance. Radius of gyration is defined as the distance from the axis of rotation to a point where total mass of the body is supposed to be concentrated. 1. It the particles of body are distributed lose to axis of rotation,the radius gyration is less. 2.It the particles are distributed away from axis of rotation ,the ...
These two factors can be separated by expressing the M I as the product of the mass ( M) and the square of a particular distance ( k) from the axis of rotation. This distance is called the radius of gyration and is defined as given above. Thus, Physical significance: The radius of gyration is less if I is less i.e., if the mass is distributed ...
Examples of Radius Ratio Rule. The ratio of radii of the ions can affect the arrangement of ions in a crystal. Moreover, the limiting ratio has to be greater than 0.414, (radius ratio greater than 0.414) to fit an octahedral arrangement of anions. In this formation, cations will be able to accommodate 6 anions.
Define radius of curvature. The radius of curvature of a spherical mirror is the radius of the circle of which the spherical mirror is a part. It can also be defined as the distance between the centre of curvature of the mirror and the pole of the mirror on the principal axis. The radius of curvature is also a measure of how curved the mirror is.
Solution. Verified by Toppr. The ionic radius is the measure of an atom's ion in a crystal lattice. It is half the distance between two ions that are barely touching each other. Since the boundary of the electron shell of an atom is somewhat fuzzy, the ions are often treated as though they were solid spheres fixed in a lattice.
