Question

electron bombardment 1. Sample injected 4. Charged particles passing through mag. field are deflected perpendicular to field. Amount of deflection related to mass. strong magnet 11. a) Atoms of which isotope, 20 Ne, Ne, and 1 Ne, would have the most inertia? b) Atoms of which isotope, 10 Ne, Ne and Ne, would be the most deflected? Which would be the least deflected? c) On the previous graphic, which stream, A, B, or C, is most deflected from a straight line path? d) Associate the stream letters A, B, and C with the isotopes 7 Ne, 10 Ne, and 10 Ne. 268

Answer 1

a) Inertia is directly related to mass. If mass is higher, inertia will also be higher. Here ₁₀²²Ne has highest mass. Hence it will have highest inertia. Similarly ₁₀²⁰Ne has lowest mass and hence will have lowest inertia.

b) Species with lowest mass will be deflected the most. Here ₁₀²⁰Ne has least mass and hence it will be deflected the most. ₁₀²²Ne has most mass and hence deflected the least.

c) The above line is deflected the most.

d) The above line is ₁₀²⁰Ne and the line below it is ₁₀²¹Ne and the bottom line is ₁₀²²Ne
