(b) In the periodic table, the transition elements and Group 1 elements are 6 points metals. Some of the properties of two transition elements and two Group
1 elements are shown in the table below. Use your own knowledge and the
data in the table above to compare the chemical and physical properties
of transition elements and Group 1 elements. (6 marks so ensure you write
enough points) *

explanation:

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
