Answer: oxygen
There is the s,p,d and f blocks, from groups 1-2 that is the s block, 13-18 that’s the p block, 3-12 is the d block and the f would be lanthanide(#57-71) and actinide (#89-103).

a. the ratio of mass to charge of an electron
Explanation:
The experiment permitted the direct measurement of the ratio of mass to charge of an electron.
- The charge to mass ratio of an electron was determine by accelerating a beam of cathode rays in magnetic and electric fields.
- No matter the gas used in the tube or the nature of the material of the electrodes, the rays were found to have constant charge to mass ratio of 1.76 x 10¹¹coulombkg⁻¹.

I use the acronym LEO for oxidation reactions. This stand for: Lose electrons Oxidation, so when oxidation occurs, electrons are lost. Due to electrons having a negative charge, substance undergoing oxidation have a more POSITIVE charge.
Pls Thank + Branliest its good for my ego :P
