Web1: Explain physical reaction along with examples. Answer: A change in which a substance undergoes a change in its physical properties is called a physical change. For example; melting of ice. 2: Explain chemical reaction along with examples. Answer: A change in which one or more new substances are formed is called a chemical reaction. WebChemical properties. Since the alkali metals are the most electropositive (the least electronegative) of elements, they react with a great variety of nonmetals. In its chemical reactivity, lithium more closely resembles Group 2 (IIa) of the periodic table than it does the other metals of its own group. It is less reactive than the other alkali ...
