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.

Answer from: cutie777

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.

hey there!

mass = 6.75 g

volume = 9 cm³

therefore:

d = mass / volume

d = 6.75 / 9

d = 0.7 g/cm³

Answer from: Quest

Ch4 and ph3 are both covalent since they are composed both of non-metals. ch4 is non- polar because of london forces and has a geometry of tetrahedral ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
