Atomic Structure and Electrons
1 Electrons
1.1 they have a relative mass of about 0
1.2 they have a charge of -1
1.3 they do the chemistry of the atom, especially the ones in the furthest shells
2 Atomic Structure
2.1 Nucleus
2.1.1 Protons
2.1.1.1 have a relative charge of +1
2.1.1.2 have a relative mass of 1
2.1.1.3 the number of protons dictates the element
2.1.2 Neutrons
2.1.2.1 have no charge
2.1.2.2 have a relative mass of 1
2.2 Electron Shells
2.2.1 they are the different energy levels of the electrons
2.2.1.1 an very 'energetic' electron would be in the furthest electron shell from the atom
2.2.2 the amount of electrons in each shell is restricted to...
2.2.2.1 2, 8, 8, 8, 8.......
2.2.2.1.1 its 8 continuously until element 22, from then on you can have 18
2.3 atoms are mostly empty space
2.4 Isotopes
2.4.1 Equation for average atomic mass:
2.4.1.1 (atomic number z X percentage of abundance z) + (atomic number q X percentage of abundance q) / 100
3 Calculating the numbers of P, N and E from the atomic no. and mass no.
3.1 Mass Number
3.1.1 is always larger than the atomic number
3.1.2 is the number of protons + neutrons in the atom
3.2 Atomic Number
3.2.1 is always smaller than the mass number
3.2.2 is the number of protons in the atom
3.2.3 is the number of electrons in the atom
3.3 to calculate the neutrons...
3.3.1 Neutrons = Atomic Number - Mass Number
