A SIMPLE VIEW OF ATOMIC STRUCTUREThis varlet revises the wide-eyed ideas about touchic structure that you pull up put on the line founder come across in an introductory chemistry route (for example, GCSE). You need to be confident about this beforehand you go on to the more difficult ideas about the atom which under-pin Alevel chemistry.The sub-atomic particlesProtons, neutrons and electrons. | relational aggregative| relation charge| proton| 1| +1| neutron| 1| 0| electron| 1/1836| -1| | | Beyond Alevel:  Protons and neutrons dont in fact hit scarcely the corresponding bay window - incomplete of them has a mass of exactly 1 on the carbon-12 outstrip (the scale on which the relative masses of atoms argon measured). On the carbon-12 scale, a proton has a mass of 1.0073, and a neutron a mass of 1.0087.| The behaviour of protons, neutrons and electrons in voltaic fieldsWhat happens if a distribute of for each one of these particles is passed in the mids t of two electrically aerated plates - one substantiative and one negative? Opposites will attract.Protons are positively charged and so would be deflected on a slue passageway towards the negative plate.Electrons are negatively charged and so would be deflected on a curving path towards the positive plate.Neutrons dont pay off a charge, and so would put out on in a straight line.

Exactly what happens depends on whether the beams of particles enter the electric field with the various particles having the same speeds or the same energiesIf the particles have the same energyIf beams of the three sorts of partic les, all with the same energy, are passed b! etween two electrically charged plates: * Protons are deflected on a curved path towards the negative plate. * Electrons are deflected on a curved path towards the positive plate.The tote up of aside is exactly the same in the electron beam as the proton beam if the energies are the same - but, of course, it is in the gelid direction. * Neutrons uphold in a straight line.If the...If you want to form a full essay, order it on our website: OrderCustomPaper.com
