The first ionization energy, of a carbon atom is 1.81 aj. what is the wavelength of light, in nanometers, that is just sufficient to ionize a carbon atom?

109.8 nm

Explanation:

The first ionization energy of a hydrogen atom is,

And Plank's constant,

And the speed is,

Now the formula for energy will be,

Put all the variable after rearranging for lambda.

Therefore the wavelength of light is 109.8 nm to ionize a carbon atom .

the force required to move the cart is divided by three or 33.33 n.
