Question

why neutral atom can only be attracted not show repulsion??

Answer 1

Atoms which have unfilled octate have tendency to combine with others to attain a stable form by fulfilling the octate. But, atoms which already have 8 electrons in their valance shell do not show any tendency to combine with others. As we know about the inert gases. So, in a way they are not attracted by others elements.

Answer 2

well its not true if we keep source nearby it neutral atom get attracted

Answer 3

Suppose the source is a magnet. And we keep iron filings nearby it, then they get atrracted to the magnet although they were neutral in the first place.

Answer 4

iron fillings contain charge in it always i guess.. (:

Answer 5

That is a result of polarization, isn't it? A neutral atom contains equal amounts of both charges. When it is placed near a charged substance, the charges in the neutral substance opposite to that charge assemble near the charged substance. So, the net result is an attraction.

Answer 6

i don't get the question well,the atom is attracted by what?

Answer 7

agree with mani that is the exact ans of this qn :)

Answer 8

go through it @konchana u ll get wat mani is tryin to say and wat i asked here ok

Answer 9

Initially iron fillings are not charged as I knew. Infact, none of the materials are charged at the first place. I agree with mani as well.

Answer 10

oh means ironfilling dont contain charge? as i also dunno but when i did xperiment i remeber it contains just a querry of mine r u sure??

Answer 11

that is exactly what i was going to post but i wasn't sure u meant attracted by another charged particle.

Answer 12

np freind :)

Answer 13

A magnetic field always has an electric field perpendicular to it. They're two faces of the same coin - They go hand in hand. So, I don't think you can say that iron filings don't have charge. They've got unpaired electrons, after all.

Answer 14

I was actually sticking to the loss of electrons and thereby gaining positive charge. And about polarization and unpaired electrons, obviously these are right. Agreed Mani. :)
