A normal element is just about any element u can find in the periodic table
However, a transition element is an element which belongs to the d-block of the periodic table i.e, from group 3 to group 12.
It is called as a transition element because it is between the s-block and the p-block elements. There is a transition from the s-block to the p-block where s-block has metals and p-block has non-metals. So the block between these 2 is called the transition block which consists of the transition elements since there is a transition from metals to non-metals.
Normal elements includes both metals and non metals where as transition elements are only metals
Normal elements have their only last shell incomplete wherese transition have last two shells incompletely filled.
Normal elements are placed on the side of the periodic table whereas transition elements are at the middle of the periodic table.
