- TL;DR Summary
- The quotient charge-mass of the electron is 1000 times greater than the one of the ion of hydrogen

hello

Witch of these are certain sentences?

a-[tex]\dfrac{e}{m_e}>\dfrac{H^{-}}{m_{H^{-}}}\cdot{1000}[/tex]

b-[tex]\dfrac{e}{m_e}>\dfrac{H^{+}}{m_{H^{+}}}\cdot{1000}[/tex]

The first accurate measurement of [tex]e/m[/tex] was made by english physicist J.J. Thomson in 1897, who demostrated that the quotient charge-mass of the electron is 1000 times greater than the one of the ion of hydrogen.

But it was cation or anion?;

This implied that electrons represent a very small portion of the mass of an atom.

Thanks!
