Compound Table Activity Find 10 items at home that you think are either elements or compounds. In the first column titled "Item Picture", write or draw the item (e.g., salt, water, iron, oxygen, etc.). In the second column titled "Element or Compound?", identify whether the item is an element (like gold, oxygen, iron) or a compound (like water, sugar, vinegar). In the third column titled "Reason", explain why you identified the item as an element or compound. Example: Water - Compound – It is made of hydrogen and oxygen. Iron - Element - It is made of only one type of atom.

To complete your Compound Table Activity, here's how you can identify elements and compounds using 10 common household items:

Table Salt

Element or Compound? : Compound
Reason : Table salt is chemically known as sodium chloride (NaCl), which is made up of sodium and chlorine atoms.


Water

Element or Compound? : Compound
Reason : Water is a compound consisting of hydrogen and oxygen (H2O).


Baking Soda

Element or Compound? : Compound
Reason : Baking soda is sodium bicarbonate (NaHCO₃), made from sodium, hydrogen, carbon, and oxygen.


Iron Nail

Element or Compound? : Element
Reason : Iron nails are composed of iron (Fe), which is a pure element.


Sugar

Element or Compound? : Compound
Reason : Table sugar or sucrose (C12H22O11) is made of carbon, hydrogen, and oxygen.


Aluminum Foil

Element or Compound? : Element
Reason : Aluminum foil is made from aluminum (Al), an element.


Vinegar

Element or Compound? : Compound
Reason : Vinegar contains acetic acid (CH3COOH), which is made of carbon, hydrogen, and oxygen.


Oxygen (Air)

Element or Compound? : Element
Reason : Oxygen (O2) is one of the gases in the air and is a pure element.


Hydrogen Peroxide

Element or Compound? : Compound
Reason : Hydrogen peroxide (H2O2) consists of hydrogen and oxygen elements.


Copper Wire


* **Element or Compound?**: Element
* **Reason**: Copper wire is made of copper (Cu), an element found on the periodic table.

Each of these items is identified as either an element or a compound based on its chemical composition. Elements are made of only one type of atom, whereas compounds consist of two or more different elements chemically bonded together.
