In summary, the conversation discusses the properties of a hydrogen atom in its lowest energy state, including the proton nucleus, electron charge and mass, and orbit radius and speed. The topic then shifts to determining the speed of a separate electron needed to ionize the hydrogen atom during a collision, with the final state resulting in all particles at rest and far from each other. The conversation also mentions the use of the equation for kinetic and potential energy, and the conversion to electron volts.

Homework Statement



A H-atom when in its lowest energy state consiste of a proton nucelus of charge +e and an electron of charge -e and mass 9.11e-31. In the Bohr model of the atom, the electron moves around the nucleus in an aprrox. circular orbit of radius .51e-10m. The speed of the electron when in this lowest energy orbit is 2.2e6m/s. Determine the speed that another electron far from the hydrogen atom must have in order to ionize the h-atom during a collision. In the final state, the two electrons and proton are considered at rest and very far from each other. Convert the answer to energy units of electron volts.

Homework Equations



K(i)+Ug(i)+Uq(i)+W=K(f)+Ug(f)+Us+Uq(f)+W(friction)

The Attempt at a Solution



I set is up as .5mv(i)^2-(kappa)(e^2)/radius=0. I came up with 3.26e6m/s but one, something about this setup is bugging me and two, how do I convert to electron volts?

Nevermind. After consulting my excellent, omniscient professor, I learned I have the right set up and he explained the electron volt stuff. Thanks!
 

1. What is the definition of "Energy Needed to Ionize a H-atom"?

The energy needed to ionize a H-atom, also known as ionization energy, is the minimum amount of energy required to remove an electron from a neutral hydrogen atom, resulting in the formation of a positively charged ion.

2. Why is the energy needed to ionize a H-atom important?

The energy needed to ionize a H-atom is important because it provides insight into the stability and reactivity of atoms. It also plays a crucial role in chemical reactions and the formation of chemical bonds.

3. How is the energy needed to ionize a H-atom determined?

The energy needed to ionize a H-atom is determined experimentally by measuring the amount of energy required to remove an electron from a hydrogen atom. This is typically done using spectroscopic techniques.

4. What factors affect the energy needed to ionize a H-atom?

The energy needed to ionize a H-atom is affected by factors such as the distance between the electron and the nucleus, the nuclear charge, and the shielding effect of other electrons in the atom. It also varies depending on the specific energy level of the electron being removed.

5. How does the energy needed to ionize a H-atom compare to other elements?

The energy needed to ionize a H-atom is relatively low compared to other elements due to its small atomic size and low nuclear charge. This makes hydrogen a highly reactive element, as it requires less energy to remove an electron and form a positively charged ion.
