The meaning of covalent bonds being directional is that atoms bonded covalently prefer specific orientations in space relative to one another. As a result, molecules in which atoms are bonded covalently have definite shapes. The reason for this directionality is that covalent bonds are formed by sharing.

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Aug 11, 2015. Only when two atoms of the same element form a covalent bond are the shared electrons actually shared equally between the atoms. bond and a triple bond, it is the most stable because it has a lower level of reactivity meaning less vulnerability in losing electrons to atoms that want to steal electrons.

The central C–ON bonds in the alkoxyamine derivatives reversibly cleave and reform upon heating, and a mixture of.

Ionic vs. Covalent Bonding. Compounds form when elements bond chemically. There are two main types of chemical bonds: covalent and ionic (electrovalent).

Feb 6, 2018. Covalent bonds are directional, meaning that atoms so bonded prefer specific orientations relative to one another; this in turn gives molecules definite shapes, as in the angular (bent) structure of the H2O molecule. Covalent bonds between identical atoms (as in H2) are nonpolar—i.e., electrically.

COVALENT BONDING – SINGLE BONDS. This page explains what covalent bonding is. It starts with a simple picture of the single covalent bond, and then modifies it slightly for A'level purposes. It also goes on to a more sophisticated view involving hybridisation. This isn't required by many UK-based syllabuses at this level.

Covalent bond. The covalent bond is defined as a region of relatively high electron density between nuclei that arises, at least partly, from the sharing of electrons and produces an attractive force and characteristic internuclear distance (McNaught and Wilkinson, 1997).
