Particle P is negatively charged and Particle Q is positively charged. Particle P is an electron orbiting around the positively charged nucleus which is Particle Q.
We know that in an Atom :
[tex]\clubsuit[/tex] Electrons Revolve around the Nucleus
[tex]\clubsuit[/tex] Electrons are Negatively Charged
[tex]\clubsuit[/tex] The Nucleus Contains Protons and Neutrons.
[tex]\clubsuit[/tex] Protons are Positively Charged
[tex]\clubsuit[/tex] Neutrons are Neutral in Charge (No Charge)
Given Statement about Particle P is that it revolves around the nucleus of the atom.
As Electrons revolve around the Nucleus, We can conclude that Particle P is Electron
Given Statement about Particle Q is that it is a Charged particle inside the Nucleus.
We know that Nucleus Contains Both Protons and Neutrons inside it. But as Neutrons have no charge, they cannot be a Charged Particle. As Protons are Positively Charged, The Charged Particle inside the Nucleus is Proton ⇒ Particle Q is Proton.
Now Let us study the given Options :
1st Option : Particle P will repel Particle Q
1st Option Cannot be True as Particle P is an Electron which is Negatively charged and Particle Q is a Proton which is Positively Charged, Both P and Q will Attract Each other.
2nd Option : Particle P is an Electron and Particle Q is a Neutron
2nd Option Cannot be True as we found that Particle P is a Electron and Particle Q is a Proton.
3rd Option : Particle P is greater in number than Particle Q in a neutral atom
3rd Option Cannot be True - Because in a Neutral atom, Number of Electrons is Equal to Number of Protons ⇒ Number of Particles P should be Equal to Number of Particles Q in a Neutral Atom.
4th Option : Particle P is negatively charged and Particle Q is positively charged.
4th Option is True. Because We know that Particle P is a Electron and Electrons are Negatively charged and Particle Q is a Proton which is Positively charged.
So, the Correct Statement is :
Particle P is negatively charged and Particle Q is positively charged.
