Atom H-2 Diagram: Label Quarks & Leptons

Click For Summary

Homework Help Overview

The discussion revolves around sketching a diagram of the Helium-2 atom, specifically labeling its quarks and leptons. Participants are exploring the composition of the atom, including the arrangement of protons, neutrons, and electrons.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the quark composition of protons and neutrons, with some confusion regarding the correct isotope of helium being referenced. There are attempts to clarify the number of quarks and the role of leptons in the atom.

Discussion Status

The conversation is ongoing, with participants providing insights into the structure of the atom and correcting misunderstandings about the isotopes. Some guidance has been offered regarding the quark arrangement, but there remains uncertainty about the specific isotope being discussed.

Contextual Notes

There is confusion regarding the notation for helium isotopes, with participants questioning whether the original poster is referring to Helium-2 or Helium-3. The discussion also touches on the short half-life of Helium-2, which may influence the context of the problem.

Sketch a diagram of the atom H-2, using the appropriate quarks and leptons. Label the particles in your diagram. I don;t knoq how to do this because my book does not have any example of this...:(

OK, protons and neutrons have three quarks each, up, up, down for the proton and down, down, up for the neutron. Up quarks have charge +2/3 and down quarks have charge -1/3.

H-2 has a proton and a neutron in the nucleus, and one electron in it's first shell, so you just need to represent the six quarks in the nucleus and the one electron in orbit.

sorry its He-2...even though i don;t have any idea how to do this...i am guessing...u and d are the quarks...(3 on top and 2 on the bottom of He). so there are 2 protons and 1 neutron...each proton will have 2 u and 1 d , neutron will have 1 u and 2 d. and lepton is electron which is 2 ...
 
Helium-2 will have two protons and no neutrons then, and as I said, a proton has two up quarks and 1 down quark, also referred to as u and d yes.

The electron is a lepton yes, but does ont consist of any quarks, it is an elementary particle.

Edit: are you sure the question asks for Helium-2 though? He-2 has a very very short half life, only 3*10^-27 seconds.
 
yes its written as 3 on top and 2 at the bottom of He...so this makes it He-2 right?
 
No, that makes it He-3. The number of nucleons is 3, the atomic number is 2 (which is true for all isotopes of Helium). Helium-3 consists of two protons and one neutron, plus two electrons in orbit since it is an electrically neutral atom (as opposed to an ion).
 
:)thanks
 
Happy to help.
