The Isotope Notation occur by adding the Superscript showing Mass Number and Subscript showing Atomic Number to the Left of the Element Symbol.

Example,

                                                 ᵇₐX
                        
                                   Where;
                                                b = Mass Number
                                                a = Atomic Number
                                               X  = Symbol
For Hydrogen Isotopes:

1) Protium: 1 Proton , 0 Neutron

                                                ¹₁H

2) Deuterium: 1 Proton , 1 Neutron

                                                ²₁H

3) Tritium: 1 Proton , 2 Neutron

                                                ³₁H

Why is the wavelength of 633 nm used to analyze the standard solutions and drink samples?
RUDIKE [14]

Answer:

Corresponding with orange light, is the wavelength that blue solutions absorb the most.

Explanation:

If light is diffused through a solution of a given color, emerges of light from another wavelength is consumed and fades away. However, the wavelength of light relating to the color of such a solution is transferred. The color of the light is consumed is usually the contrasting one being transferred. As seen in a color wheel where, blue complement orange, red complement green, and yellow complement violet.

Thus, for a blue substance in solution, its complementary color is said to be orange, Given that the wavelength of orange color varies from 600 - 640 nm where it's maximum absorbance is approximately 633 nm. This wavelength is what is employed when analyzing the standard solutions and drink samples.
