Q1.
In the periodic table, the transition elements and Group 1 elements are 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.

Physical Properties
Transition elements are strong, hard metals with high melting points and high densities.
Group 1 elements are soft, have low melting points, and low densities – they’re much lighter and easier to cut.
Chemical Properties
Transition elements don’t react quickly – they are less reactive and can react slowly with water or oxygen.
They’re also used as catalysts, form ions with different charges, and make coloured compounds.Group 1 elements, on the other hand, are very reactive, especially with water and non-metals.
They are not used as catalysts, always form a +1 ion, and their compounds are usually white or colourless. -
Compare the physical and chemical properties of transition elements and Group 1 elements.
Transition elements are strong, hard metals with high melting points and high densities. In contrast, Group 1 metals are soft, have low melting points, and low densities – some even float on water!
Chemically, transition metals react slowly and are less reactive, while Group 1 metals react quickly, especially with water. Transition metals can form ions with different charges and make coloured compounds. They are also used as catalysts. Group 1 metals only form +1 ions, their compounds are usually white or colourless, and they are not used as catalysts.
