add behavior problems

All gases, irrespective of their chemical composition, obey certain laws that govern the relationship between the volume, temperature and pressure of the gases. A given mass of a gas, under definite conditions of temperature and pressure, occupies a definite volume. When any of the three vari..

Like all other first elements of the groups, oxygen also differs from its family members. The anomalous behavior of oxygen is due to its (i) small size (ii) high value of ionization energy and electronegativity (iii) absence of d-orbitals in the valence shel..

Anomalous Behavior of Oxygen - Like all other first elements of the groups, oxygen also differs from its family members. The anomalous behavior of oxygen is due to its (i) small size (ii) high value of ionization energy and electronegativity (iii) absence of d-orbitals in the va..

Some hydroxides behave both as bases and acids under different conditions, e.g., hydroxides of zinc, lead and aluminium. These hydroxides are only weakly basic, but like other bases, they still combine with acids to form salt and wate..

Lithium displays most of the characteristic properties of group to which it belongs i.e. the alkali metals group (Group 1..

Al, Ga, In and Tl exhibit a well-defined aqueous chemistry in their tripositive states. Species like [M(OH) 4 ] - , [M(H 2 O) 2 (OH) 4 ] - , [M(OH 2 ) 6 ] 3 + for M = Al, Ga, In, exist in aqueous solution. Al, Ga. In and T1 ions exist as octahedral aqua ions, [M(OH 2 ) 6 ] 3 + in aqueous solution a..

Because of extremely small size of its atom and high electronegativity, boron differs in its properties from other elements of the group. On the other hand, it resembles silicon to some extent due to diagonal relationship. The following properties illustrate the anomalous behavior o..
