Chemistry crayon labels from the QueInteresante Etsy store.

About the project: 

Children play and draw with crayons practically every day, so why not make the experience more educational? This listing is for a set of 48 labels to stick in the crayons in a basic 48 pack of crayons so that while children are coloring, they are also exposed to the names of chemicals that will make those colors! So instead of thinking “I want green” they will think “I want Barium Nitrate Ba(NO3)2 Flame” and then when they take chemistry in high school and their teacher sets some gas on fire and it makes a green color and they ask the class what chemical it was your student will know it was Barium! Genius!

WANT!!

OK, yeah, this is pretty cool.

And then bonded that hydrogen to another carbon.

tumblrsbetterthanpumprs: as a celebration of my recent return to the worlds of chemistry and academia, let’s share a moment of appreciating how interesting looking molecular orbitals are.  (in case you are vaguely curious as to what they are, each one is a depiction of where the electrons orbit around in a molecule.)

Structures of solid oxygen under high pressure: At 1.9 TPa, oxygen polymerizes and assumes a square spiral-like structure, which is semi-conducting (top). With increasing pressure, the polymer exhibits metallic properties (zig-zag chain-like phase, mid). Then, the structure changes into a metallic layer phase (bottom). The coloured areas represent the charge density in one layer of the structure. (Credit: © Jian Sun)

kidsneedscience:

The word amine (and the adjectival form amino) has a long and surprising history-starting with the Ancient Egyptian king of the gods, Amon Ra. Starting a little closer to home, the word amino was coined in 1887 by shortening the word ammonia which itself was a modern Latinization of the Ancient Greek ammoniakos. The word ammoniakos was the Ancient Greek word to denote ‘of Amon’, from the name of the King of the Egyptian pantheon, Amon-Ra. What is the connection between amines and the King of the Gods? When Swedish chemist Torbern Bergman (1735–1784) coined the word ammonia in 1782, he was thinking of the Roman Temple of Jupiter in Libya, also known to the Greeks as the Temple of Zeus and formerly known as the Temple of Amon-Ra, a source of salt deposits containing ammonium chloride. The building blocks of life and foundation of modern biology, medicine, and genetics are named after the Ancient Egyptian King of the Gods!

Today, amines are defined as organic compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are derivatives of ammonia, wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group.

I was just wondering about this!

lostinretrosynthesis: Edman degradation - A simple reaction used in peptide sequencing. This reaction labels the amino-terminal aminoacid of the sequence without breaking the bonds of the entire sequence like other reactants (such as the Sanger reactant) do. This way the aminoacids can be sequenced one by one. Unfortunately, this method is too slow and unpractical for large petides with longer amnoacidic chains, so it is usually applied in combination with other sequencing reactants.
