The tendency of an atom to attract the bonding or a shared pair of electrons
What are the factor on which ionic bond formation depends?
Ionic bond formation mainly depends upon three factors –
i Low ionization energy
– elements with low ionization enthalpy have greater tendency to form an ionic bonds. ii High electron gain enthalpy – high negative value of electron gain enthalpy favours ionic bond.
What does covalent bond formation depend on?
A covalent bond involves a pair of electrons being shared between atoms. Atoms form covalent bonds in order to reach a more stable state. A given nonmetal atom can form a single, double, or triple bond with another nonmetal. Which type of bond is formed between the atoms depends on
their numbers of valence electrons
.
What factors the formation of ionic bond explain with examples?
Ionic bonds involve a cation and an anion. The bond is formed when
an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation
. ... One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom.
What are the factors that influence the formation of an ionic bond and covalent bond?
-
Ionization energy: It is defined as the amount of energy required to remove the most loosely bound electron from an isolated gaseous atom of an element. ...
-
Electron affinity: ...
-
Lattice energy:
What factors make the formation of ionic bonds energetically favorable overall?
What factors make the formation of ionic bonds energetically favorable overall? The favourable factors influence in ionic bond formation are as follows: (i)
Low ionization enthalpy of metal atom
. (iii) High electron gain enthalpy (Δeg H) of a non-metal atom. (iv) High lattice energy of the compound formed.
On what factors does the formation of cation depends upon?
1) Small size of cation: Smaller size of cation greater is its
polarizing power
i.e. greater will be the covalent nature of the bond. (2) Large size of anion: Larger the size of anion greater is its polarizing power i.e. greater will be the covalent nature of the bond.
What is ionic bond write its two factors?
(i)
Low ionization enthalpy of metal atom
. (ii) The two ion must be different and should possess opposite charge. (iii) High electron gain enthalpy (Δ
eg
H) of a non-metal atom. (iv) High lattice energy of the compound formed.
What is ionic bond give example?
The definition of ionic bond is when a positively charged ion forms a bond with a negatively charged ions and one atom transfers electrons to another. An example of an ionic bond is
the chemical compound Sodium Chloride
.

What is covalent bond give example?
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. ...
Water molecule (H2O) One oxygen atom joins with
two hydrogen atoms. ... Carbon dioxide (CO2) One carbon atom joins with two oxygen atoms.
Which compound has a covalent bond?
Covalent compound examples include
water, ammonia, chlorine gas, and nitrogen gas
. Covalent compounds or molecular compounds are chemical compounds made of elements connected by covalent bonds.
What are the Favourable conditions for formation of ionic bonds?
Favourable conditions for the formation of ionic bond are
low ionization energy of metal and high electronegativity of non-metal
. Explanation: An ionic bond is defined as the bond formed due to transfer of one or more number of electrons from one atom to another.
What is the key difference between covalent and ionic bonds?
In covalent bonds,
atoms share electrons
, whereas in ionic bonds atoms transfer electrons. The reaction components of covalent bonds are electrically neutral, whereas for ionic bonds they are both charged. This explains why sodium chloride (salt) conducts electricity when dissolved — its components are charged.
What happens first in the formation of an ionic bond quizlet?
It is formed
when an atom gains electrons
. An ion with a positive charge. It is formed when an atom loses electrons.
Which steps in the formation of an ionic bond are endothermic?
There is a 3-step process that we can use to approach the energy involved in ionic solution formation. 1)
Breaking apart the ionic compound is endothermic
and requires energy. 2) Hydrating cation is exothermic and therefore releases energy. 3) Hydrating the anion is exothermic and also releases energy.
