Why does an element form a double or triple bond?

Covalent bonding occurs when electrons are shared between atoms. Double and triple covalent bonds occur when four or six electrons are shared between two atoms, and they are indicated in Lewis structures by drawing two or three lines connecting one atom to another.

Why are some atoms double bonded?

Double bonds form when two atoms must share four electrons in order to achieve the octet rule. The octet rule states that atoms will lose, gain, or share electrons to have eight valence electrons. Double bonds form quite frequently in nature, and are usually made by nonmetals like carbon, nitrogen, and oxygen.

Why do some atoms bond to themselves?

Atoms form chemical bonds to make their outer electron shells more stable. The type of chemical bond maximizes the stability of the atoms that form it. Covalent bonds form when sharing atoms results in the highest stability. Other types of bonds besides ionic and covalent chemical bonds exist, too.

What do double and triple bonds form?

When pairs of electrons are shared between the atoms it results in the formation of covalent bonds. If two pairs of electrons are shared between atoms, then the double bond is formed and represented by two parallel lines. When three pairs of electrons are shared between two atoms then a triple bond is formed.

How does a triple bond form?

A triple bond is formed when two atoms are sharing three pairs of electrons. Triple bonds between atoms are often represented by three parallel lines. It is important to note that electrons are shared in pairs.

What two elements can form single double and triple bonds?

Carbon-Carbon Bonds Carbon can form single, double, or even triple bonds with other carbon atoms. In a single bond, two carbon atoms share one pair of electrons. In a double bond, they share two pairs of electrons, and in a triple bond they share three pairs of electrons.

Why do some atoms bond and others don t?

Why do some atoms are reluctant to bond with other atoms? As explained above, NOBLE GASES are very reluctant to share, gain or lose electrons to form a chemical bond ie they do NOT readily form a covalent or ionic bond with other atoms.

What is meant by triple bond explain the formation of triple bond between two atoms of nitrogen to give nitrogen molecule?

The bond formed between two atoms through the sharing of three electron pairs is called a triple bond. Therefore, in N2 molecules, two nitrogen atoms share 3 electrons with each other, thus acquiring the stable structure and forming a N2 molecule with triple bonds.

What is a triple bond in chemistry?

A Triple Bond is formed when a molecule shares three pairs of electrons between two atoms. It is the least stable of the three general types of covalent bonds, because losing an electron is very vulnerable. Triple bond symbols: triple lines (≡) indicates a triple bond. Triple bond example: N2, C2H2 etc.

Why do atoms form single bonds?

Hence, to attain stability, atoms achieve their nearest noble gas configuration. Now to attain their nearest noble gas configuration, they share required no. of electrons from single or multiple atoms. This leads to the formation of single bond, double bond or triple bond.

Why are single bonds more stable than double bonds?

This bond type is relatively weak and has a smaller electron density than a double bond and a triple bond, but is the most stable because it has a lower reactivity level. It means that the loss of electrons to atoms is less susceptible. Single bond symbol: A single line represents a bond between two atoms (i.e., involving one electron pair)

Why do double bonds occur in covalent compounds?

Generally, for covalent bonds between second row atoms, the reason is an interaction between the p orbitals of the constituent atoms. A double bond, as in ethene H2C=CH2, arises from one combination of the s orbitals and one combination of the p_y orbitals.
