Question

a more reactive metal displaces a less reactive metal from its salt solution. using this concept, describe an experiment to show that among the metals, zinc, iron and copper, zins is the most reactive metal where as copper is the least reactive metal.

Answer 1

Metals occupy the bulk of the periodic table. The alkali metals are a series of chemical elements in the periodic table. Alkali metals comprise group 1 in the periodic table along with hydrogen. Alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr). The group 2 elements in the periodic table are called alkaline earth metals. Alkaline earth metals are beryllium (Be), magnesium (Mg) calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). Group1 and group 2 elements are together called s-block elements. Elements of group 3 to 12 are transition elements. These are also metallic in nature and are called transition metals. They are also called d-block elements. Non-metallic elements occupy the right side of the periodic table. A diagonal line from boron to polonium separates metals from non-metals.

Answer 2

Caesium, the most reactive metal in the periodic table, reacts extremely violently – hence why it can't be demonstrated in a classroom! This can be compared to other common metals, such as iron and copper, which produce no reaction when dropped into water.
