Concept explainers
Interpretation:
From the description of the element fluorine given below, the physical and chemical properties have to be identified.
“Fluorine is a pale-yellow corrosive gas that reacts with practically all substances. Finely divided metals, glass, ceramics, carbon and even water burn in fluorine with a bright flame. Small amounts of compounds of this element in drinking water and toothpaste prevent dental cavities. The free element has a melting point of
Concept Introduction:
Chemical property:
The property that describes the reactivity of a material and in the process forms new and different substances.
Physical property:
The property that can be measured without changing the composition of the sample.
