Beryllium deffers in properties from other elemets of its own group but shows resemblance wih aluminium because of

Beryllium differs from other alkaline earth metals because of

The first element of a group differes from its congeners, i.e other members of the group in many ways. These difference may be due to the following i) Small size of atom and ion ii) High electronegetivity iii) Non-availability of low lying d-orbitals The first element of a group shows resemblance with the second element of the adjacent group on the right. This is known as diagonal relationship Metal (M)+ N_(2) rarr "Nitride" underset("hydroysis")overset(H_(2)O)rarr NH_(3) . Metal (M) can be

Fluorine the I^(st) member of group 17^(th) differs from the other members of the group in many respects due to the following reasons. (i) Small size (ii) Hight EN (iii) absence of 'd' orbitals (iv) its Delta H dissociation in molecular form of X_(2) is the least. The most basic among the following

Beryllium resembles the following element more than the members of its own family

PASSAGE - IV : In periodic table metals show high reducing ability and non-metals show high oxidizing ability. The properties of metalloids in between metals and non-metals. In a group from top to bottom the reducing ability increases and in a period from left to right oxidizing ability increases. In which of the following set both are metalloids
