10 Questions
What is the primary requirement for a molecule to form?
More stable than individual atoms
Which type of elements have low ionization potentials and easily give up electrons?
Electropositive elements
How do atoms attain a stable electronic configuration in bond formation?
By sharing electrons
What type of bond is formed between two electronegative elements?
Covalent bond
What determines the type of bond formed between two elements?
Number of electrons in the outermost shell
What is the primary requirement for an ionic bond to form?
One species must have surplus electrons and the other must have deficient electrons
Why do all substances having surplus electrons and species having deficient electrons not form ionic bonds?
Because in an ionic bond, one species must be a cation and the other an anion
What is the energy required to remove an electron from a neutral atom called?
Ionization energy
What determines the ease of removing an electron to form a cation?
Ionization energy of the element
Why is an ionic bond not considered a true bond?
Because there is no proper overlap of orbitals
Study Notes
Bond Formation
- A molecule forms when atoms gain, lose, or share electrons to attain a stable electronic configuration.
Ionization Potentials
- Elements with low ionization potentials (e.g., alkali metals) easily give up electrons.
Bonding Mechanisms
- Atoms attain a stable electronic configuration in bond formation by gaining, losing, or sharing electrons.
Covalent Bonds
- A covalent bond is formed between two electronegative elements when they share electrons to attain a stable electronic configuration.
Bond Type Determination
- The type of bond formed between two elements is determined by the difference in their electronegativities.
Ionic Bonds
-
The primary requirement for an ionic bond to form is a large difference in electronegativity between two elements, resulting in electron transfer.
-
Not all substances having surplus electrons and species having deficient electrons form ionic bonds due to the energy required for electron transfer.
Ionization Energy
-
The energy required to remove an electron from a neutral atom is called ionization energy.
-
Ionization energy determines the ease of removing an electron to form a cation.
Ionic Bond Characteristics
- An ionic bond is not considered a true bond because it does not involve the sharing of electrons, but rather the transfer of electrons.
