The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other.

Carbon-12 makes up 99% of an atom, carbon-13 makes up 1% and carbon ... Radioactive atoms decay into stable atoms by a simple mathematical process. Half of the available atoms will change in ...

In these drawings, every line is a bond and every bend is a carbon atom. Most hydrogen atoms are not shown, and it is assumed each carbon has enough hydrogens so that each carbon has four bonds.

Explain that a water molecule has two hydrogen atoms and one oxygen atom. Ask students to use Snap Cubes to make a water molecule. Then show students the animated Snap Cube model of a water molecule.

Graphyne is a crystalline form of carbon that is distinct from both diamond and graphite. Unlike diamond, where each atom possesses four immediate neighbors, or graphite, where each atom has three ...

Tourism is responsible for 8% of all global carbon emissions; this simple menu tweak could help reduce the industry’s environmental footprint. Sometimes, the smallest things can make all the ...

The alkanes are a homologous series with a structure based on a carbon chain - each carbon atom forms four covalent ... long chains compared with smaller simple molecules. This means that polymers ...

"Global warming" is so simple that it risks misrepresenting ... The most famous greenhouse gas, carbon dioxide, forms when a carbon atom bonds with O2 (oxygen). Methane, a greenhouse pollutant ...

The effect is to remove a hydrogen atom from the backbone carbon atom at the targeted spot ... chiral centers on a wide variety of relatively simple carboxylic acid starting compounds containing ...

The function of many biologically active molecules requires the presence of carbon-nitrogen bonds in ... The essence of chemical synthesis is to transform simple starting materials into complex ...
