In order to understand hydrogen bonds, you must first understand the nature of a special type of covalent bond called the polar covalent bond. 1. In polar covalent bonds, the electrons are more strongly attracted to one of the two atoms, usually oxygen or nitrogen, than to the other atom. 2.
o We need a double or triple bond o Correct Lewis Structures: • Types of Bonds o Single Bond- a covalent bond in which _____pair of electrons is shared by two atoms o Double Bond- A covalent bond in which _____ pairs of electrons are shared by two atoms
Dative covalent bonds . A dative covalent bond (also known as a coordinate covalent bond) is a description of covalent bonding between two atoms in which both electrons shared in the bond come from the same atom. This happens when a Lewis base (an electron donor) donates a pair of electrons to a Lewis acid (an electron acceptor).
An oxygen atom can share two electrons with another oxygen atom, however, making two covalent bonds between the SAME two atoms a double bond. This is why the formula for oxygen molecules is O2 two oxygen atoms an oxygen molecule Practice: Draw dot and cross diagrams for these molecules: Carbon dioxide CO2 Ethene C2H4 It is also possible to have a triple bond, with three shared pairs of electrons.
Sometimes atoms share more than one pair of electrons between them in order to form stable molecules. Two dashes, corresponding to two pairs of electrons, and three dashes, corresponding to three pairs of electrons, are used to represent double and triple bonds, respectively. G.
In chemistry, a single bond is a chemical bond between two atoms involving two valence electrons.That is, the atoms share one pair of electrons where the bond forms. Therefore, a single bond is a type of covalent bond.When shared, each of the two electrons involved is no longer in the sole possession of the orbital in which it originated. Rather, both of the two electrons spend time in either ...

Nitrogen has five valence electrons, so it needs three more valence electrons to complete its octet. A nitrogen atom can fill its octet by sharing three electrons with another nitrogen atom, forming three covalent bonds, a so-called triple bond. The triple bond formation of nitrogen is shown in the following figure.
Triple bonds The elements in group 15, such as Nitrogen , have 5 valence electrons and need three electrons for a noble-gas configuration, so they bonded by three pairs of electrons. The Nitrogen atom can make three single bonds with other elements such as Hydrogen or a triple bond with a similar Nitrogen atom.
