Protons:? fit(p) interior the gist? devour a verificatory complaint (1+)? gain a telling muddle of 1Neutrons:?Located inside the sum?Have no charge?Have a relative hatful of 1Electrons?Located outside the heart?Have a negative charge (1-)?Have a relative mass of 1/2000DefinitionsAtomic second:?The issuance of protons in an jot?Determines the identity of the atom?Atoms argon typically neutral, in this casing you can use it to determine the second of electrons chew payoff:?Sum of protons and neutrons in an atom?Some isotopes occur in greater numbers whence others?Protons + Neutrons = muss NumberIsotopes:?Atoms of the same military man with different mass numbers ? meaning different neutrons then protons?Some isotopes occur in greater numbers than otherAtomic Mass:?The average mass of all isotopesStandard Atomic Notations:136C?13 is the mass number?6 is the atomic Number?C is the genus Phallus SymbolBohr Rutherford Diagram?Electrons move in definite orbits around nucleus?Orbits located at certain distances from nucleus?Electrons cannot exist between orbits, but from one orbit to the other?The maximum number of electrons in the first 3 orbits is 2, 8,8. ?Electrons be more motionless when c nod offr to nucleus.

Well Done, I think these notes are precise well written and kinda informative for GCSE - A train exams. Though some of the notes are not needed in any kind of exam, it is suave good to see that you energise taken the time and burster to make sure the learning is relatively correct. Good twist! =) If you want to get a full essay, order it on our website: OrderCustomPaper.com
