Answer:
» An electron is lighter than a proton.
Step-by-step explanation:
![{ = \: \sf{an \: electron \: has \: formula \: \: }}{ \bf{ {}^(0)_( - 1)e }}](https://img.qammunity.org/2022/formulas/physics/college/r21m5fedwh6fp0f5m8h15eygxmbi3xr8s0.png)
hence it's mass number is zero
![{ = \: \sf{an \: electron \: is \: helium \: particle \: \: }}{ \bf{ {}^(4) _(2)He }}](https://img.qammunity.org/2022/formulas/physics/college/mn1h5p21qxpdbfbxtfx9hp24smdwzzk2v1.png)
hence it's mass number is 4
Therefore, proton is heavier than electron
» An electron has a small charge magnitude than a proton.
Step-by-step explanation:
An electron has charge of -1 while proton has charge of +2, therefore electron is less deflected by any energetic fields than a proton
