five basic elements relationship

Borax is slightly hydrolyzed in solution. As boric acid is a weak acid, the solution is alkaline in nature...

Ammonia molecule has a strong tendency to donate its lone pair of electrons of nitrogen to other molecules. Thus, it acts like a strong Lewis base. In aqueous solutions, NH 3 ionizes in accordance with the reaction...

Some elements of second period show similarities with elements of the third period present diagonally to each other, even though they belong to different groups. The similarity in properties of elements present diagonally is called diagonal relationship. Thi..

Lithium has a diagonal relationship with magnesium and both have similarities in some of their characteristics. The atomic radius of both elements is close; lithium (152 pm) and magnesium (160 pm). Both have almost similar electronegativities (Li = 1.0, Mg = 1.2) Both L..

The oxides of elements in a period become progressively more acidic as one goes from left to right in a period of the periodic table. For example, in third period, the behavior of oxides changes as follows:..

/p. This is de Broglie wave equation. De-Broglie's hypothesis attributing a dual particle-wave character to matter appears very strange at first sight. Since it is very much against the direct evidence of one's senses at the macroscopic level. But at the level of the atom, the behavior of matter ha..

Basic fluxes like lime (CaO), magnesium oxide (MgO) are used to remove acidic gangue such as SiO 2 ...

A buffer solution containing relatively large amounts of a weak base and its salt with a strong acid, is termed as a basic buffer. Such buffers have pH on the alkaline side i.e., pH is higher than 7 at 298 K. The pH of a basic buffer is given by the equation:..

Carbon dioxide reacts with basic oxides such as potassium oxide, sodium oxide and calcium oxide to form carbonates. ..

2 and MO type oxides. Their chemistry is characterized by (+2) oxidation state. In general, the heavier p-block elements favor low oxidation states. The most important element of group 15 is phosphorus. It exists in white, red and black allotropic forms. It forms molecular ..
