Which set of elements has a strong tendency to form cations? Or which of the elements are the most electropositive elements?

The elements belonging to Group 1 and group 2 of periodic table has the strong tendency to form cations. The reason behind this tendency is that the elements belonging to group 1 and 2 have one and two valance electrons respectively. By loosing the valence electrons, they will aquire noble gas configuration. It is easy to release 1 and 2 […]

Its never too late

We can if we wish, Returning is never so tough, It’s not mandatory, But it’s a choice, You can say openly, Who suppress your voice, And decision you make, Are not of iron, or steel, You can break them whenever you feel, And life is not a movie, Where you can rewind the reel, The time has its pace, Just […]

What are the Characteristics of a lone pair ?

What are the characteristics of a lone pair? Characteristics of a lone pair Lone pair are the pair of electrons that do not take part in any chemical bond. They affect the symmetry of molecule or the shape of molecule as they interfere with the other electrons of the molecule . The electrons of lone pair repel the other bond […]

WHY THE IONIC REACTIONS ARE FASTER?

How are reactions related to chemical bonds? The type of bond has a great effect on the rate of reaction or speed of reaction. Here we are going to discuss why and how it happens, First of all in case of ionic compounds:- Lets take example of Sodium hydroxide and Hydrochloric acid NaOH (aq) + HCl (aq) →  NaCl + […]

Covalent bonds versus ionic bonds.

There are two types of bonds that can be formed Either by sharing of electrons , that is covalent bond. Or 2. By transfer of electrons , that is ionic bond. Now the question is that , why to go for covalent bond? An important aspect of ionic bond is that the difference of electronegativity between the two elements must […]

Neutralisation reaction

The reaction between an acid and base to give salt and water is called neutralisation reaction. here in the following reaction we can easily see how Hydrochloric acid is reacting with sodium chloride NaOH + HCl ———> NaCl + H2O the nature of salt formed is dependent on the type of acid or base , if there is any difference then […]
