Harmful compound sulfur dioxide (SO4)
Harmless constituent elements: Oxygen(O) and Sulfur(S)
Why is it harmful: Breathing in this gas might cause breathing problems and respiratory diseases. Might also cause premature death.
Chemical Bonding: Covalent Bonding
Constituent elements:
Sulfur: Atomic number 16, a non-metallic element that is yellow in colour. It is essential for life and found in 2 amino acids, cysteine and methiodine. Used mostly as fetilizers if not gunpowder pesticides etc.
Oxygen:Atomic number 8, non-metallic gas which is found colourless in gaseous state and pale blue in liquid state. It consists of 20.8% of the atmosphere in earth and is highly reactive, thus making it form compounds with almost any other element readily.
Sulfur dioxide: Formed by burning sulfur, which is bonding oxygen with sulfur through covalent bonding.
