To convert cm-1 to electron volts (eV), you can use the formula: 1 cm-1 0.00012398 eV. This means that to convert a value in cm-1 to eV, you would multiply the value in cm-1 by 0.00012398.
To convert electron volts (eV) to centimeters (cm), you can use the formula: 1 eV 1.97 x 10-5 cm.
To convert 1 cm-1 to electron volts (eV), you can use the conversion factor of 1 cm-1 0.00012398 eV.
To calculate the energy needed to move an electron in a hydrogen atom from ( n = 3 ) to ( n = 6 ), we use the formula for the energy levels of hydrogen: [ E_n = -\frac{13.6 , \text{eV}}{n^2} ] Calculating the energies for ( n = 3 ) and ( n = 6 ): [ E_3 = -\frac{13.6}{3^2} = -1.51 , \text{eV} ] [ E_6 = -\frac{13.6}{6^2} = -0.38 , \text{eV} ] The energy difference is: [ \Delta E = E_6 - E_3 = -0.38 - (-1.51) = 1.13 , \text{eV} ] To convert this to joules, use ( 1 , \text{eV} = 1.6 \times 10^{-19} , \text{J} ): [ 1.13 , \text{eV} \times 1.6 \times 10^{-19} , \text{J/eV} \approx 1.81 \times 10^{-19} , \text{J} ] Thus, the answers are approximately ( 1.81 \times 10^{-19} , \text{J} ) and ( 1.13 , \text{eV} ).

To convert electronvolts (eV) to joules, use the conversion factor 1 eV = 1.60218 x 10^-19 Joules. Thus, 9.0 eV is equal to 9.0 x 1.60218 x 10^-19 Joules, which is approximately 1.442962 x 10^-18 Joules.
To convert electronvolts (eV) to wave numbers in reciprocal centimeters (cm-1), you can use the formula: wave number (cm-1) 8065.54 / wavelength (nm).
To find the energy in electronvolts (eV) from a given wavelength (in this case, 650 nm), you can use the formula E = hc/λ, where E is the energy in eV, h is Planck's constant (6.626 x 10^-34 J s), c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength in meters. First, convert the wavelength from nanometers to meters (1 nm = 1 x 10^-9 meters), then plug the values into the formula to calculate the energy.
Common units of energy include joules (J), calories (cal), kilowatt-hours (kWh), and electronvolts (eV).
