Q1: Define metals and non-metals based on their physical properties. Give two examples of each.

Metals are elements that generally have a shiny appearance, are malleable, ductile, and are good conductors of heat and electricity. They are solid at room temperature (except mercury). Examples: Copper (Cu), Iron (Fe) Non-metals are elements that are generally dull in appearance, brittle, and are ...

Q2: Explain the difference between the reactivity of metals and non-metals with oxygen. Illustrate with equations.

Metals generally react with oxygen to form basic oxides (metal oxides). Example: 2Mg + O2 -> 2MgO (Magnesium oxide is basic) Non-metals react with oxygen to form acidic oxides (non-metal oxides). Example: S + O2 -> SO2 (Sulfur dioxide is acidic) The oxides of metals are typically basic and t...

Q3: What is the reactivity series of metals? Arrange these metals in order of their reactivity: Copper, Magnesium, Iron, Calcium.

The reactivity series of metals is the arrangement of metals in the order of their decreasing reactivity. More reactive metals displace less reactive metals from their salt solutions. Arrangement in decreasing order of reactivity: Calcium (Ca) > Magnesium (Mg) > Iron (Fe) > Copper (Cu) Ca...
