Fe (iron), Ni (nickel), Cu (copper), Zn (zinc)


Be (beryllium), Mg (magnesium), Ca (calcium), Sr (strontium)


B (boron), Si (silicon), Ge (germanium), As (arsenic)

Respuesta :

C and D

  • Be,Mg,Ca,Sr are the alkaline earth metals and present in group 2 ,so they must have similar properties
  • B,Si,Ge,As are metalloids ,so they are also similar properties holders.

The elements of the periodic table which posses similar properties they  are, Be (beryllium), Mg (magnesium), Ca (calcium), Sr (strontium), and B (boron), Si (silicon), Ge (germanium), As (arsenic).

What is periodic table?

The periodic table is a science chart that displays chemical elements in order of atomic number.

What is element?

An element is made up of atoms with the identical count of protons in their nuclei as the other atoms in the element.

It is know that if any elements have identical number of valence electrons then such atom will be kept in identical group of the periodic table that's why Be, Mg and Ca will be kept in same group and B , Si and Ge will be kept in same group.

Therefore, on the basis of valence electron, elements will be kept in periodic table.
