Question

100 POINTS PLSS HELP ME!!!!!!!!!! Harry described two subatomic particles below: Particle P: Revolves around the nucleus of the atom Particle Q: Charged particle inside the nucleus Which of the following statements is correct based on the descriptions of each particle? Particle P will repel Particle Q. Particle P is an electron and Particle Q is a neutron. Particle P is greater in number than Particle Q in a neutral atom. Particle P is negatively charged and Particle Q is positively charged.

Answer 1

We know that in an Atom :

$\clubsuit$  Electrons Revolve around the Nucleus

$\clubsuit$  Electrons are Negatively Charged

$\clubsuit$  The Nucleus Contains Protons and Neutrons.

$\clubsuit$  Protons are Positively Charged

$\clubsuit$  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.

Answer 2

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.
