Describe varieties of elements that kind covalent bonds. Define how a covalent shortcut is formed. Distinguish in between ionic and also molecular compounds. Know the an interpretation of prefixes supplied in naming molecular compounds. Distinguish in between molecules and also compounds.

Water and diamonds - two really different materials. Water have the right to be found virtually everywhere. The is in lakes, creeks, rivers, and oceans. We get water indigenous the sky as soon as it rains. Diamonds, top top the various other hand, are very rare. They space only found in a couple of locations top top the earth and must it is in mined to end up being available. Significant diamond mines are situated in miscellaneous African countries, Australia, and Russia. The joined States has actually several underground sources of diamonds in Alaska, Colorado, Minnesota, Montana, and Wyoming, yet the just "active" U.S. Mine is the Crater the Diamonds mine in a state park near Murfreesboro, Arkansas. Because that a tiny fee, visitors have the right to dig because that diamonds. Friend won"t get rich by visiting, though - just a few hundred carats the low-grade diamonds are found each year.

The two materials do have at least one point in common. The atoms in the products are organized together by covalent bonds. This bonds consist of electrons shared between two or more atoms. Unlike ionic bonds, whereby electrons room either lost or got by one atom to form charged ions, electrons in covalent compounds are shared between the two atoms, providing rise to nature that space quite various from those viewed in ionic materials.


Molecular Compounds

Molecular compounds room hunterriverpei.comical compounds the take the form of discrete molecules. Examples include such familiar substances together water \(\left( \ceH_2O \right)\) and also carbon dioxide \(\left( \ceCO_2 \right)\) (Figure \(\PageIndex1\)). These compounds are really different native ionic compounds favor sodium chloride \(\left( \ceNaCl \right)\). Ionic link are created when metal atoms lose one or an ext of their electrons come nonmetal atoms. The result cations and anions are electrostatically attractive to each other.

So what hold the atoms of a molecule together? quite than forming ions, the atom of a molecule share their valence electron in such a method that a shortcut forms between pairs of atoms. In a carbon dioxide molecule, there room two of this bonds, each arising between the carbon atom and also one of the 2 oxygen atoms.
