Question

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.

Answer 1

X is an electron and Y is a proton

No need to thank me

Answer 2

X is an electron and Y is a proton.

Step-by-step 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
