Two different sub-atomic particles are described below:

Particle X: Carries a negative charge

Particle Y: Attracts Particle X

Which statement is true?

X is a neutron and Y is an electron.

X is a neutron and Y is a proton.

X is a proton and Y is an electron.

X is an electron and Y is a proton.

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
