chemistry
sub shells
-
- s holds a max of 2 electrons
- p holds a max of 6 electrons
- d holds a max of 10 electrons
- f holds a max of 14 electrons
- 4s always fills before 3d (except chromium and copper)
shells
- shell 1 = max of 2 electrons
- shell 2 = max of 8 electrons
-
- shell 4 = max of 32 electrons
- shell 5 = max of 50 electrons
- flourine is the most electronegative element
- the further away from fluorine an element is, the less electronegative it is
- electronegativity is a measure of the tendency for an atom to attract a bonding pair of electrons
- elements with similar electronegativity form covalent bonds
- elements with different electronegativity form ionic bonds
equations
-
-
- concentration = mass ÷ volume
periodic table
- groups correspond to the number of electrons in the outter shell
- periods correspond to the number of shells
bonds
ionic bonding
-
- strong electrostatic forces
-
oxides
- oxygen reacts with other metals and non metals to form an oxide
