Explanation:

Carbon (C) is in coal, has combustibility. Hydrogen (H) is in water, is highly flammable. Nitrogen (N) is in air, is inert. Oxygen (O) is in air, supports combustion. Phosphorus (P) is in matches, is reactive. Sulfur (S) is in gunpowder, burns readily. Loss of excessive trace - elements can disrupt biological functions, cause health problems like enzyme malfunction, weakened immune system etc.

Answer:

Element Symbol	Element Name	Common Object	Important Property
H	Hydrogen	Water	High flammability
N	Nitrogen	Air	Inertness
O	Oxygen	Air	Supports combustion
P	Phosphorus	Matches	Reactivity
S	Sulfur	Gunpowder	Readily burns

When excessive trace elements are lost, biological functions can be disrupted and health problems can occur such as enzyme malfunction and weakened immune system.
