Answer:
X is an electron and Y is a proton.
Explanation:
The particle X caries negative charge it means it have one extra electron.
When number of electrons becomes greater than protons particle have negative charge and
Particle Y attract particle X it means Y has positive charge because opposite charges attract each other and it must be a proton because proton has positive charge while neutron is neutral.
Symbol and charge of proton= P+
Symbol and charge of neutron= n0
Mass of proton=1.672623×10-27 Kg
Mass of neutron=1.674929×10-27 Kg
Symbol and charge on electron = e-
Mass= 9.10938356×10-31 Kg
