The energy of the light with a wavelength of 415 nm is not sufficient to remove an electron from a silver atom in the gaseous phase.
<h3>Energy and wavelength of light</h3>
The energy and wavelength of light are related by the formula given below:
- Energy = hc/λ
- where, E = energy
- h = Planck's constant
- c = velocity of light
- λ = wavelength of light
<h3>Calculating the energy of the light</h3>
From the data provided:
- h = 6.63 × 10^-34 Js
- c = 3.0 × 10^8 m/s
- λ = 415 nm = 4.15 × 10^-7 m
E = (6.63 × 10^-34 × 3.0 × 10^8 m/s)/4.15 × 10^-7 m
E = 4.79 × 10^-19 J
Energy of light is 4.79 × 10^-19 J
Compared with the ionization energy of silver, the energy of the light is far less.
Therefore, the energy of the light with a wavelength of 415 nm is not sufficient to remove an electron from a silver atom in the gaseous phase.

Answer:
Option b) polyatomic ions
Explanation:
Polyatomic ions are ions consisting of two or more atoms.
From the question given above, we can see that each ions consist of more than one atom as shown below:
Ions >>>>>> Number of atom present
NH4+ >>>>> 2
CO32− >>>> 2
PO43− >>>> 2
Thus, we can say that the above ions are polyatomic ions.
