Respuesta :

In periodic table of elements, they have common properties such as :

#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.

#All the elements in Group 2 have two electrons in their valence shells, giving them an oxidation state of +2.

Answer:

The correct answer is chemical properties.

Explanation:

In a group, the chemical properties are very similar, because all the elements of the group have the same number of electrons in their last or last layers. The electronic configuration of its last layer is the same, varying only the period of the element. Alkaline earth metals are harder than alkaline metals, have brightness and are good electrical conductors; less reactive than alkalines, good reducing agents and form ionic compounds.

Have a nice day!
