The goals of IYC2011 are to increase the public appreciation of chemistry in meeting world needs, to encourage interest in chemistry among young people, and to generate enthusiasm for the creative future of chemistry. The year 2011 will coincide with the 100th anniversary of the Nobel Prize awarded to Madame Marie Curie—an opportunity to celebrate the contributions of women to science. The year will also be the 100th anniversary of the founding of the International Association of Chemical Societies, providing a chance to highlight the benefits of international scientific collaboration.
IYC 2011 events will emphasize that chemistry is a creative science essential for sustainability and improvements to our way of life. Activities, such as lectures, exhibits, and hands-on experiments, will explore how chemical research is critical for solving our most vexing global problems involving food, water, health, energy, transportation, and more.
In addition, the Year of Chemistry will help enhance international cooperation by serving as a focal point or information source for activities by national chemical societies, educational institutions, industry, governmental, and non-governmental organizations.
For more information about the goals, activities, administration, and timeline of IYC 2011, please download the IYC Prospectus.
The IYC 2011 is an initiative of IUPAC, the International Union of Pure and Applied Chemistry, and of UNESCO, the United Nations Educational, Scientific, and Cultural Organization. It involves chemical societies, academies, and institutions worldwide, and relies on individual initiatives to organize local and regional activities.
hey hey heyyy, can you suggest a perfect periodic table? just a standard element one with maybe atomic masses, protons, and categories? im trying to find something to tell my class about that would be just a nice standard, yet very helpful
Nothing is perfect, not even the best of periodic tables, but this website comes so close.
Indeed, as you all might have already heard, this year’s Nobel Prize in Physics went to the discovery of Graphene. The 2010 Nobel Prize in Chemistry will be announced on the 6th of October, which is this week’s Wednesday. You can watch the live telecast here, if you happen to be awake at that time. Aren’t you excited? :D
DAD: Because the water washes the dirt away when I use soap.
DAD: Why do I use soap?
DAD: Because the soap grabs the dirt and lets the water wash it off.
DAD: Why does the soap grab the dirt?
DAD: Because soap is a surfactant.
DAD: Why is soap a surfactant?
DAD: That is an EXCELLENT question. Soap is a surfactant because it forms water-soluble micelles that trap the otherwise insoluble dirt and oil particles.
DAD: Why does soap form micelles?
DAD: Soap molecules are long chains with a polar, hydrophilic head and a non-polar, hydrophobic tail. Can you say ‘hydrophilic’?
DAD: And can you say ‘hydrophobic’?
DAD: Excellent! The word ‘hydrophobic’ means that it avoids water.
DAD: Why does it mean that?
DAD: It’s Greek! ‘Hydro’ means water and ‘phobic’ means ‘fear of’. ‘Phobos’ is fear. So ‘hydrophobic’ means ‘afraid of water’.
SARAH: Like a monster?
DAD: You mean, like being afraid of a monster?
DAD: A scary monster, sure. If you were afraid of a monster, a Greek person would say you were gorgophobic.
SARAH: (rolls her eyes) I thought we were talking about soap.
DAD: We are talking about soap.
DAD: Why do the molecules have a hydrophilic head and a hydrophobic tail?
DAD: Because the C-O bonds in the head are highly polar, and the C-H bonds in the tail are effectively non-polar.
DAD: Because while carbon and hydrogen have almost the same electronegativity, oxygen is far more electronegative, thereby polarizing the C-O bonds.
DAD: Why is oxygen more electronegative than carbon and hydrogen?
DAD: That’s complicated. There are different answers to that question, depending on whether you’re talking about the Pauling or Mulliken electronegativity scales. The Pauling scale is based on homo- versus heteronuclear bond strength differences, while the Mulliken scale is based on the atomic properties of electron affinity and ionization energy. But it really all comes down to effective nuclear charge. The valence electrons in an oxygen atom have a lower energy than those of a carbon atom, and electrons shared between them are held more tightly to the oxygen, because electrons in an oxygen atom experience a greater nuclear charge and therefore a stronger attraction to the atomic nucleus! Cool, huh?
Hi, I'm doing an art project for my AP Art class, and we had to incorporate some sort of text into our piece, and I chose to incorporate chemical structures into my piece. I was just wondering what your favourite chemicals are, structurally?
C60! You might find this website useful for your project. Good luck! :)
"Today, our English class proceeded to move our desks around to work with each other on an annotation. Four desks were moved, enclosing a square perimeter. Closed off from the group, my desk rested at one corner of the desk-made square. It was then that I realized we had formed the line structural diagram of methylcyclobutane."
