Answer:
Explanation:
from snells law we have following relation
is refractive index of air
n' - refractive index of air below
i is angle of incidence = 90 - 1.30 = 88.70^o
r is refraction angle
plugging all value in above formula
The elements found in the Group 1, or the Alkali Metal Group, have electronic configurations that end in 
.This means that they have 1 electron readily available to release in order to achieve a stable state.
When these atoms release the valence electron, they will achieve a stable state. For example, Lithium's stable state will be
and Sodium will be 
.
The oxidation state will then be +1.
The answer is C.
