P-block Elements | BORON FAMILY | Physical & Chemical Properties |by Jay Daiya Sir

Which Group IIIA elements is expected to have physical and chemical properties least similar to other members of that group?

The pair of elements that have similar chemical properties are

Elements in the same group have __ chemical properties. (similar/different).

The statement that is false for the long form of the periodic table is : 1. it reflects the sequence of filling of electrons in the order of sub energy levels s, p, d, f 2. it helps to predict the stable valency states of the elements 3. it reflects trends in physical and chemical properties of the elements 4. it helps to predict the relative ionocity of the bond between any two elements.

The first element in a group of p-block of the periodic table often displays different physical and chemical properties from the heavier members of the group. In the light of this statement give comparative explanations for the following: Nature of oxides of boron and aluminum

Which pair of elements has same chemical properties ?

Which of the following elements differs from the rest in several physical and chemical properties? (a)Li (b)Na (c)Rb (d)Cs

The first element in a group of p-block of the periodic table often displays different physical and chemical properties from the heavier members of the group. In the light of this statement give comparative explanations for the following: Action of water on C Cl_4 and SiCl_4

Two elements A and B have similar chemical properties. They don’t form solid hydrogencarbonates, but react with nitrogen to form nitrides. A and B, respectively, are :

Why do elements in the same group have similar physical and chemical properties?
