Bonsoir,

Pouvez-vous me traduire ce texte s'il vous plait?

In 1897, Sir Joseph Thomson, discovered a negatively charged particule called electron.

I've supposed that atom is electrically neutral. So my research has led me to believe that there are both positive and negative things in atoms. I set up the atom model called plum-pudding in 1904.


Merci beaucoup,
C'est pour la physique chimie.
