The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals.
What is Group 2 called What are the common properties of this group?
Alkali Earth Metals – Group 2 Elements Being a metal, they are obviously good conductors of heat and electricity. The general electronic configuration of Group 2 elements is ns2. Alkali earth metals have the capability to lose the two electrons in their outer shell.
What are Group 4 elements called?
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member.

What are transition elements and their characteristics?
Elements which in their ground state or in any of their oxidation state have partially filled d-orbital are called transition elements. The name transition given to the elements of d-block is only because of their position between s-block and p-block elements.
What are the properties of Group 3?
All the group 3 elements are rather soft, silvery-white metals, although their hardness increases with atomic number. They quickly tarnish in air and react with water, though their reactivity is masked by the formation of an oxide layer.
What is the trend of reactivity in Group 2?
As you progress down Group 2, the reactivity increases. This is due to a decrease in ionisation energy as you progress down the group. As it requires less energy to form the ions, the reactivity increases.
