joking as we all know world of chemicals portal is one of the fastest growing online chemistry portal in the world is inviting essay entries as a part of “Earth Day celebration.”
The topic for Essay Competition 2014 is “Reducing harmful chemical footprint, a reality?
The topic is focused on reducing the harmful chemical impact on Earth and making it a better place to live. We have reached to a level where the dependency on synthetic chemicals cannot be completely eliminated. Chemicals do exist in nature, they are the ones useful the mankind, but we have been manufacturing chemicals (synthetic chemicals), most of which are hazardous. This year on Earth Day, let us think of the alternatives which can reduce the dependency on the synthetic chemicals and make our Earth better and safer.
Anyone can participate irrespective of the geographical location, educational qualification etc. The word limit for essay is 600 – 800 words.
Last date of submission is – 27 April 2014
Results announcement – 5 May 2014 on Worldofchemicals website

We have learnt how electrons involve in stabilisation of an atom. What’s about Proton? Has there been no role for them? Has there been any way to express the number of protons in an atom? The answer is “YES”. Protons and neutrons are also known as the nucleons.
The number of protons in the nucleus is known as the atomic/proton number of the particular element. It is conventionally represented by the symbol Z. It is the proton/atomic number (Z) that determines the number of electrons, specific electron structure and the specific identity of an element in terms of its physical and chemical properties. Since an atom having no charge, means the number of electrons must be equal to the number of protons that is the atomic number. Hence, in an atom the atomic number is also equal to the number of electrons. Read Complete Story

How soaps really work?
Soap acts as an emulsifier, which makes it an excellent cleansing agent. An emulsifier is capable of dispersing one liquid into another immiscible liquid. Soap molecule has an ionic and non-ionic part, the non-ionic part (hydrocarbon chain) doesn’t naturally mix with water, soap can suspend oil/dirt in such a way that it can be removed… Read more
