Answer:
Ionization potential of C⁺⁵ is 489.6 eV.
Wavelength of the transition from n=3 to n=2 is 1.83 x 10⁻⁸ m.
Explanation:
The ionization potential of hydrogen like atoms is given by the relation :
.....(1)
Here <em>E</em> is ionization potential, <em>Z</em> is atomic number and <em>n</em> is the principal quantum number which represents the state of the atom.
In this problem, the ionization potential of Carbon atom is to determine.
So, substitute 6 for <em>Z</em> and 1 for <em>n</em> in the equation (1).
<em> E = </em>489.6 eV
The wavelength (λ) of the photon due to the transition of electrons in Hydrogen like atom is given by the relation :
![\frac{1}{\lambda} =RZ^{2}[\frac{1}{n_{1} ^{2}}-\frac{1}{n_{2} ^{2} }]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Clambda%7D%20%3DRZ%5E%7B2%7D%5B%5Cfrac%7B1%7D%7Bn_%7B1%7D%20%5E%7B2%7D%7D-%5Cfrac%7B1%7D%7Bn_%7B2%7D%20%5E%7B2%7D%20%7D%5D)
......(2)
R is Rydberg constant, n₁ and n₂ are the transition states of the atom.
Substitute 6 for Z, 2 for n₁, 3 for n₂ and 1.09 x 10⁷ m⁻¹ for R in equation (2).
![\frac{1}{\lambda} =1.09\times10^{7} \times6^{2}[\frac{1}{2 ^{2}}-\frac{1}{3 ^{2} }]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Clambda%7D%20%3D1.09%5Ctimes10%5E%7B7%7D%20%5Ctimes6%5E%7B2%7D%5B%5Cfrac%7B1%7D%7B2%20%5E%7B2%7D%7D-%5Cfrac%7B1%7D%7B3%20%5E%7B2%7D%20%7D%5D)
= 5.45 x 10⁷
λ = 1.83 x 10⁻⁸ m
Answer:
asteroids are broken pieces of rock and are small compared to actual planets also asteroids travel in "belts" and not there own course
Explanation:
that was my best suggestion
Based on the chemical reaction, Carbon reacts with Oxygen would yield Carbon Dioxide, we can imply that the "<span>Atoms are always conserved during chemical reactions." It is one of the fundamental concepts in chemistry wherein the mass is always conserved in a reaction since it can't be created nor destroyed.</span>
Answer:
n = 1.7*10²² electrons.
Explanation:
- As the current, by definition, is the rate of change of charge, assuming that the current was flowing at a steady rate of .151 A during the 5 hours, we can find the total charge that passed perpendicular to the cross-section of the circuit, as follows:
⇒ Δq = I * Δt = 0.151 A * 18000 s = 2718 C
- As this charge is carried by electrons, we can express this value as the product of the elementary charge e (charge of a single electron) times the number of electrons flowing during that time, as follows:
Δq = n*e
Answer:
The closer a planet is to the sun, the shorter its period of revolution. The farther away a planet is from the sun, the longer its period of revolution.
