Understanding the periodic table of elements
By: Elaine Sihera
Everyone would have learnt about the periodic table of elements at some point in their lives, most likely at school in science lessons. If one is not keen on science, it would have been a passing experience to fulfil the mandatory association with it. However...

Helium is a so-called "noble" gas, meaning that under almost any conditions, it does not chemically react with other elements. It contains a full outer valence shell of electrons, making each atom very reluctant to either donate or share valence electrons with surrounding elements to...

Nobel Laureate Ernest Rutherford is known for being one of the first men to have split the atom. This father of modern nuclear physics also discovered protons, theorized about the existence of neutrons, and revised science’s view on the structure of the atom. All...
The uses of helium
By: Glen Brizius
Helium is a so-called "noble" gas, meaning that under almost any conditions, it does not chemically react with other elements. It contains a full outer shell of electrons, meaning that it is willing to neither donate nor share its electrons with neighboring atoms. This very...
How we benefit from chemical engineering
By: Madhusoodanan K.P
One of the most important benefits of chemical engineering is that it holds the potential to offer several job opportunities for individuals.From pharmaceuticals,fertilizers and chemicals,oil and gas,food processing and so on,several areas of industry and business utilize the basics of...
The newest elements on the periodic table
By: Effie Moore Salem
The newest elements on the periodic table are those numbered 111 through 118. On the paper chart issued by The American Society, these elements are blue; not the brighter hued blue or the violet tinted blue, but a powdery blue. On my chart which is...
Green chemistry: Pesticides
By: Glen Brizius
Green chemistry (see other articles on this site for an application of its principles) continues to be a major research topic for chemical industry. The need to quickly and easily generate compounds of chemical interest while minimizing toxicity and the generation of undesired byproducts is...
How the periodic table is used in chemistry
By: Brian Dodson
The periodic table organizes the chemical elements according to periodic trends in the chemical activity which has been discovered over centuries of research and discovery. The main value of the periodic table in chemistry is that the chemical properties of an element can be predicted...
What is the next leap in physics?
By: Rodney Bartlett
Like Dr. Michio Kaku in the book “Physics of the Impossible”, I believe that time travel is possible but unlike him, I don't believe in parallel universes. I hope to show that the combination of belief in time travel/disbelief in parallel universes validates string...
How to read the electron configuration chart
By: Brian Dodson
The essence of chemistry is the redistribution of atomic valence electrons. This redistribution lowers the total energy of the atoms, thereby driving chemical reactions. The electronic configuration of an atom completely specifies the properties of all the electrons. Knowing the properties of an element's electrons...
