Which energy has the shortest wavelength?
Gamma Rays
Which transition has the highest frequency?
(ii) Energy and frequency are directly related. Therefore the highest-energy transition is also the one with the highest frequency (n = 3 —> n = 1).
What is the transition Imagen of maximum frequency?
5th spectral line of Humphery series.
Which emits the photon of lowest frequency?
hydrogen atom
Which of the following transition in hydrogen atom will require the highest amount of energy?
ΔE1>ΔE2 and therefore the first transition would require the most significant amount of energy input.
What color is the emission line with the lowest energy?
red
What is the potential energy of hydrogen atom?
The values En are the possible value for the total electron energy (kinetic and potential energy) in the hydrogen atom. The average potential energy is -2*13.6 eV/n2 and the average kinetic energy is +13.6 eV/n2.
Which electronic transition is a hydrogen atom?
The electron energy is hydrogen atom is given by Enth=−2.
How do you find the energy of hydrogen spectrum?
The observed hydrogen-spectrum wavelengths can be calculated using the following formula:
- 1λ=R(1n2f−1n2i) 1 λ = R ( 1 n f 2 − 1 n i 2 ) ,
- hf=(13.6 eV)(1n2f−1n2i)
- hfhc=fc=1λ=(13.6 eV)hc(1n2f−1n2i)
- 1λ=R(1n2f−1n2i)
Which series has the highest energy in hydrogen spectrum?
lyman series
What is wrong about atomic emission spectrum of hydrogen?
Answer: The number of lines does not equal the number of electrons in an atom. For example, hydrogen has one electron, but its emission spectrum shows many lines. Hence, the photons of an emission spectrum represent a variety of possible energy levels.
How many energy levels are there in hydrogen?
1
What is first excitation energy?
The minimum energy required to excite an electron from the ground state of an atom to any excited state is called excitation energy. Thus, the energy required to excite an electron in the ground state to the first excited state is called the first excitation energy and so on.
What is the formula for excitation potential?
Excitation Potential : Potential difference through which an electron must be accelerated from rest so that its kinetic energy becomes equal lo excitation energy of any state is called excitation potential of that state. 1st excitation energy = 10.2 eV. 1st excitation potential = 10.2V.
What is the first excitation energy of hydrogen atom?
The first excitation energy of the hydrogen atom is 10.2eV.
What should be the first excitation potential of li2+?
In hydrogen atom, energy of first excited state is-3.4 eV.
What is the value of Z for Li2+?
The first excited state of hydrogen is n = 2 (n = 1 is the lowerst-energy, or “ground” state), which from the Rydberg equation has an energy equal to E(n = 2; Z = 1) = -R/4 = -3.4 eV.
What would be the radius of 2nd excited state in Li2+?
Answer: The radius of 2nd excited state in ion is 70.53 pm.
Which is the first excited state of lithium?
The first excited state is 1.848 eV above the ground state. Uniform, high density plasmas on the order of a few meters in length are needed for the next generation of plasma based particle accelerator boosters. Such plasmas are currently beyond the state of the art.
What is the electron configuration of the second excited state of lithium?
1s23s1.
What is the excited state of Li2+?
Answer. Hey There, Here Lithium has been given in a +2 excited state.
What is the electron configuration for Li+?
Therefore the Li electron configuration will be 1s22s1.
What noble gas has the same electron configuration as Li+?
noble gas helium
What is the difference between Li and Li+?
Li has fewer protons than Li+ Li has more protons than Li+ Li has fewer electrons than Li+ Li has more electrons than Li+
