9. Identify which properties of each of the following elements make them ideal for their uses. KIU A (a) copper and aluminum for pots and pans (b) silver and gold for jewellery (C) argon in double-glazed windows for homes

Each element has its own unique properties. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. The atomic number of an element is equal to the number of protons that element contains. The mass number is the number of protons plus the number of neutrons of that element. Therefore, it is possible to determine the number of neutrons by subtracting the atomic number from the mass number.
