In
polar covalent bonds
, the electrons are shared unequally, as one atom exerts a stronger force of attraction on the electrons than the other. The ability of an atom to attract a pair of electrons
In
a polar covalent bond
, the electrons are unequally shared by the atoms and spend more time close to one atom than the other.
A Polar Covalent Bond
is created when the shared electrons between atoms are not equally shared. This occurs when one atom has a higher electronegativity than the atom it is sharing with. … As a result, the shared electrons will be closer to the atom with the higher electronegativity, making it unequally shared.
Covalent bonds form when electrons are shared between atoms and are attracted by the nuclei of both atoms. In
pure covalent bonds
, the electrons are shared equally. In polar covalent bonds, the electrons are shared unequally, as one atom exerts a stronger force of attraction on the electrons than the other.
Triple bond, in chemistry, a covalent linkage in which two atoms share
three pairs of electrons
, as in the nitrogen molecule, N

What type of bond are electrons transferred?
Ionic bond
, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
A covalent 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.
Is a bond formed when there is sharing of electrons?
Covalent bonds
are the most important means of bonding in organic chemistry. The formation of a covalent bond is the result of atoms sharing some electrons. The bond is created by the overlapping of two atomic orbitals [1].
Single bonds occur when
two electrons
are shared and are composed of one sigma bond between the two atoms. Double bonds occur when four electrons are shared between the two atoms and consist of one sigma bond and one pi bond.
Which nonmetal appears to attract electrons the most?
Fluorine
attracts electrons better than any other element. The table below shows the electronegativity values for the elements. The electronegativity scale was developed by Nobel Prize winning American chemist Linus Pauling.
How do you know if a bond is single double or triple?
If the shared number is one pair of electrons, the bond will be a
single bond
, whereas if two atoms bonded by two pairs (four electrons), it will form a double bond. Triple bonds are formed by sharing three pairs (six atoms) of electrons. These sharing electrons are commonly known as valence electrons.
What is the weakest type of bond in chemistry?
The ionic bond
is generally the weakest of the true chemical bonds that bind atoms to atoms.
Which bond is the strongest?
Covalent Bonds
Another type of strong chemical bond between two or more atoms is a covalent bond. These bonds form when an electron is shared between two elements. Covalent bonds are the strongest (*see note below) and most common form of chemical bond in living organisms.
Are double bonds stronger?
Experiments have shown that
double bonds are stronger than single bonds
, and triple bonds are stronger than double bonds. Therefore, it would take more energy to break the triple bond in N
2
compared to the double bond in O
2
.
Why are electrons transferred?
Electrons are not affected by the strong force, and so they only get trapped by the
electrical attraction to the nucleus
which is much weaker in ionized atoms. Therefore it is easier for electrons to move away from one atom to another, transferring charge.
