What are the trends in chemical reactivity of the elements?

WebAlkali metals are highly reactive metals because of their large size and low ionization enthalpy. Their reactivity increases on moving down the group. Reactivity towards air: When these metals are kept in dry air, they get tarnished due to the formation of oxides, which become hydroxides on reacting with moisture. WebThe alkali metals react with water to produce a metal hydroxide and hydrogen. For example, sodium reacts with water: sodium + water → sodium hydroxide + hydrogen … WebIn a group, metallic properties increase and non-metallic properties decrease throughout the group. 4. Chemical reactivity: The chemical reactivity of an element can be clearly understood by studying the reaction of the element with oxygen and halogens. Elements combine with oxygen to form oxides. the movie the lake
