Types of elements in s, p, d and f blocks

S-block:

• The s-block elements are metals .
•  Metals are usually solids at room temperature.
• Metals usually have high melting and boiling points. They are good conductors of heat and electricity.
•  They are malleable (can be flattened into thin sheets by hammering) and ductile.

P-block:

• The p-block contains metals, metalloids (or semi-metals) and non-metals.
• Non-metals are usually solids or gases at room temperature with low melting and boiling points (boron and carbon are exceptions).
                                                                            
  
• They are poor conductors of heat and electricity.
•  Most nonmetallic solids are brittle and are neither malleable nor ductile.
• The change from metallic to non-metallic character is not abrupt as shown by the thick zig-zag line in.
• The elements (e.g., silicon, germanium, arsenic, antimony and tellurium) bordering this line and running diagonally across the Periodic Table are semi-metals. Their properties are in between those of metals and non-metals.

d-block and f-block

• The d-block elements are metallic in nature and they form alloys.
• They are said to form covalent bonding as well as the metallic boding.
• The f-block elements, Lanthanides and actinides, are silvery white metals having tensile strength.
