- S,P,D,F
- S-Block Elements
- Outermost electrons in S subshells
- E- lost to form +ve ions
- Metal such as Na, Mg, K and Ca are very reactive and form stable ionic compounds with non-metals
- LOW M.P AND B.P
- Conduct Electricty - metallic bonding with sea of e- between atoms.
- H and He also in s-block
- P-block Elements
- Group 3,4,5,6,7,8
- Contains all non-metals and metalloids and some metals
- Form Covalent bonds with other non-metals and ionic bonds with metals
- Majoirity do conduct electricity. Graphite is an exception
- Metalloids - poor electricity conduction, metallic in nature
- All metals in the p-block conduct electricity, heat but not strong metals
- D-block Elements
- Between grp 2&3
- A.k.a transition metals
- Everyday metals e.g. copper, iron, silver
- Much less reactive than grp 1&2 metals
- Inner D orbitals being filled + outer S subshell is full
- F-Block Elements
- E- being added in F subshells
- Top row - 14 elements - lanthanides are all similar
- 2nd row - Actinides are all radioactive
- Only up to uranium are naturally occurring
- Other synthesised by chemists
- Very unstable
- Half-lives only milliseconds
- S-Block Elements
