By Colby Smith and Joe Rennison The market for U.S. government bonds, the bedrock of the global financial system, continued to shudder on Thursday, as President Trump’s bill to extend expensive ...

Living Proof’s formula requires heat to activate the covalent cross-linking, so, essentially, read and follow your product’s instructions. Did you know: Ford says that bonds in the hair are so ...

This new bond also challenges our fundamental understanding of what exactly constitutes a covalent bond. ‘Roughly speaking, the cause of this bond is the proximity of the atoms due to the rest of the ...

This, of course, poses quite a conundrum, as many believe single-electron chemical bonds can’t exist. That’s because all of the current known covalent bonds—where atoms connect by sharing ...

A research team from Hokkaido University has confirmed a century-old theory by discovering a stable single-electron covalent bond, known as a sigma bond, between two carbon atoms. This unique bond ...

Using an X-ray diffractor to study the sigma bond. Credit: Yusuke Ishigaki Covalent bonds, the very backbone of organic compounds, are formed when two atoms share a pair of electrons. Back in 1931, ...

Covalent bonds, in which two atoms are bound together by sharing a pair of electrons, form the scaffolding that underpins the majority of organic compounds. In 1931, the Nobel Laureate Linus ...

Begin to answer this question by using hydrogen as an example. Project the animation Covalent bond in hydrogen. Make sure students see that each hydrogen atom has 1 proton and 1 electron. Remind ...

The Explain It with Atoms and Molecules and Take It Further sections of the activity sheet will either be completed as a class, in groups, or individually depending on your instructions. Look at the ...

Pain relief drugs like aspirin, and penicillin, one of the world’s first antibiotics, are popular examples of covalent drugs. A covalent bond is a permanent bond between two atoms. When chemists make ...

Add a description, image, and links to the coordinate-covalent-bonds topic page so that developers can more easily learn about it.
