The correct option is the first one, which is: Negatively charged electrons.

 J.J Thomson was British physicist who discovered the electron in 1897, by his experiment with "cathode ray tubes". For this work and contribution to science, he was awarded the Nobel Prize for physics in 1906.

Answer:

negatively charged electrons  

Explanation:

According to Dalton's Model, matter is made up of tiny particles known as atoms. Electrons were not known at that time. Thomson gave the plum pudding model which describe atom to be over all neutral with equal distribution of negatively charged electrons in the region of positive charges.

Thus, negatively charged electrons were a characteristic of the Thomson's model of the atom but not the Dalton's model.
