Single, Double, and Triple Bonds - Science Notes and Projects
网页2021年7月20日 · Carbon and members of the oxygen family of elements (the chalcogens) participate in double bonds. Examples of double bonds are O 2 (oxygen, O=O), CO 2 (carbon dioxide, O=C=O), and C 2 H 2 (ethylene, H-C=C-H). The double bond consists of one sigma (σ) bond and one pi (π) bond.
What a Double Bond Means in Chemistry - ThoughtCo
网页2019年10月2日 · A double bond is a type of chemical bond in which two electron pairs are shared between two atoms. This type of bond involves four bonding electrons between atoms, rather than the usual two bonding electrons involved in a single bond.

网页In π π orbitals, the electron density lies above and below the axis connecting the bonded atoms. The combination of \simga \simga and π π bonding orbitals produces a double bond. Double bonds are indicated by two lines, for …
COVALENT BONDING - DOUBLE BONDS - chemguide
网页A double covalent bond is where two pairs of electrons are shared between the atoms rather than just one pair. Some simple molecules containing double bonds. Oxygen, O2. Two oxygen atoms can both achieve stable structures by sharing two pairs of electrons as in the diagram. The double bond is shown conventionally by two lines joining the atoms.

Covalent Bond Definition and Examples - Science Notes and Projects
网页2023年6月13日 · A covalent bond is a chemical bond between two atoms where they share one or more pairs of electrons. Usually, sharing electrons gives each atom a full valence shell and makes the resulting compound more stable than its constituent atoms are on their own. Covalent bonds usually form between nonmetals.
