Explanation: When gentle ray emerges in the prism, it travels from denser to rarer medium. Based on the rule of refraction, it'll bend from the traditional. Therefore, angle of refraction are going to be greater than angle of incidence at that surface area.
Lack of an electron from an atom brings about the formation of the cation. A cation is lesser than its parent atom because it has fomer electrons while its nuclear charge remains exactly the same. As an example, The atomic radius of sodium (Na) is 186 pm and atomic radius of sodium ion (Na+) = ninety five pm.
