1. Activity Series of Metals

Mnemonic: "Popular Scientists Can Make A Zoo In The Low Humid Country More Satisfactorily"

Interpretations:

• P: Potassium (K)
• S: Sodium (Na)
• C: Calcium (Ca)
• M: Magnesium (Mg)
• A: Aluminium (Al)
• Z: Zinc (Zn)
• I: Iron (Fe)
• T: Tin (Sn)
• L: Lead (Pb)
• H: Hydrogen (H) (not a metal but used as a reference point in the series)
• C: Copper (Cu)
• S: Silver (Ag)
• M: Mercury (Hg)

The mnemonic lists metals in descending order of reactivity.

2. Physical Properties for Metals

Mnemonic: "Lucky Cats Make Delicious Desserts Happily"

• Luster: Shiny surface
• Conductivity: Heat & electricity flow
• Malleability: Hammer into sheets
• Ductility: Draw into wires
• Density: High mass for volume
• High melting & boiling points

3. Physical Properties of Non-Metals

Mnemonic: "Lazy Pets Break Low Low Vases"

For Non-Metals:

• Lack of luster: Dull appearance
• Poor conductors: Heat & electricity flow less
• Brittleness: Crumble or break easily
• Low density: Lower mass for volume
• Low melting & boiling points
• Variety of states: Solid, liquid, or gas

4. Common Non Metals

Mnemonic: “Happy Charlie’s Ox Always Sees Pretty Bears”

This stands for:

• Hydrogen (H)
• Carbon (C)
• Oxygen (O)
• Argon (Ar)
• Sulfur (S)
• Phosphorus (P)
• Bromine (Br)

These mnemonics can help make it easier to recall the elements in each category!
