Which orbital is non directional?
They are non directional because they are spherical in shape and probability of finding electrons at a particular distance from the nucleus is same in all directions.
Define metallic bond and write its properties.
The simultaneous electrostatic attraction between rhe kernels and the mobile electrons which holds the kernels together is called metallic bond.
It is a weak bond.
Electrons here are delocalized.
It causes metals to display the following characteristics.
1. Electrical Conductivity
2. Thermal conductivity
3. Luster
4. Malleable and ductile
