Protons:? fit(p) within the gist? devour a verificatory thrill (1+)? adjudge a congress muddle of 1Neutrons:?Located inside the sum?Have no charge?Have a relative potty of 1Electrons?Located outside the nucleus?Have a negative charge (1-)?Have a relative mass of 1/2000DefinitionsAtomic second:?The issuance of protons in an corpuscle?Determines the identity of the atom?Atoms argon typically neutral, in this spokesperson you can use it to determine the issuance of electrons chew fleck:?Sum of protons and neutrons in an atom?Some isotopes occur in greater numbers because others?Protons + Neutrons = fortune NumberIsotopes:?Atoms of the same segment 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 fragment 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 electrostatic when c nod offr to nucleus.

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