Excuse Me!

Has there been a 6 marker discussing the different types of radiation (alpha, beta, gamma) yet? P2

Could you give me the model answer of motor effect for a 6 marker by any chance? This topic confuses me :awesome:

I swear people in the exam are going to look at me all weird when I'm trying to do Fleming's left hand rule,
I really hate physics as well :frown:

Once I nearly fell off my chair in the exam trying to do the left hand rule -_-

I just use the left hand palm rule, which doesn't really need you to twist your hand into weird positions :tongue:

That there is a nucleus, there is space in an atom and that the nucleus is positively charged ? :s-smilie:

Yep, that's it.

Also, I think that you're supposed to know that most of the mass is concentrated in the nucleus and the rest is mostly empty space, but that's pretty much it :smile:

Yes in January 2014.

I didn't think there had been a jan 14 paper? Is it just on the aqa website?

I looked and there isn't one?

I've given the results of the experiment, and the corresponding conclusions you're expected to draw:
- the majority of the alpha particles passed straight through - the atom is mostly empty space
- some alpha particles were reflected at small angles - the nucleus is positively charged (as it was repelled by the positively charged gold nuclei in the foil)
- a few alpha particles were deflected at very large angles - there is a large central mass within the atom (the nucleus)

This contradicted the 'plum pudding' model which stated differently that the electrons were suspended within the positive charge, which had no empty space.

Thanks

What's the palm rule?

I swear if that rule comes up I'm gonna burst out laughing at how ridiculous everyone looks

Not yet, but this is the question:

How have you got access to it? Could you send it to me?

It's basically like the left hand rule, but you put your fingers perpendicular to your thumb and open your palm. The thumb represents the current and the fingers represent the magnetic field, and your palm should face in the direction of the force.

It just means that you don't have to twist your hand into lots of weird shapes :tongue:
