An electron in the hydrogen atom makes a transition from an energy state of principal quantum number ni to the n = 2 state. if the photon emitted has a wavelength of 657 nm, what is the value of ni?

Explanation:

The Rydberg equation gives the wavelength λ for the transitions:

where

R= the Rydberg constant (1.0974 ×10⁷ m⁻¹) and

Data:

λ = 657 nm

Calculation:  

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
