Homework Help Overview

The discussion revolves around calculating the atomic mass of an atom based on the diameter of its nucleus, specifically comparing it to the known diameter of a proton. Participants are exploring concepts in nuclear physics related to atomic structure and mass calculations.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are attempting to relate the diameter of a nucleus to its atomic mass by considering the density of nuclei. Questions arise about how to calculate the atomic mass for a nucleus with a given diameter and the implications of volume ratios between different nuclei.

Discussion Status

The discussion is active with participants sharing their findings and questioning the assumptions about nuclear density and volume. Some guidance has been offered regarding the relationship between the volume of the nucleus and the number of nucleons, but no consensus has been reached.

Contextual Notes

Participants are working under the assumption that the density of nuclei is uniform and similar to that of a proton. There is also a reference to a previous question that may relate to this topic.

If you assume that the density of nuclei are about the same and equal to the density of a proton, then all you have to know is the diameter of a proton _1^1H

i found that the diameter of a proton is 1x10^(-15)m with atomic mass 1, but how do i calculate the atomic mass of an atom with diameter 8x10^(-15)m?

What is the ratio of volume of the larger nucleus to that of the proton? If each nucleon (a proton or neutron) has the same volume, what does that tell you about the number of nucleons in the larger nucleus?
