16 Questions
What type of bond is formed when there is an electronegativity value of 1.2
Polar Covalent
How do the physical properties of ionic compounds compare to those of covalent compounds?
Ionic compounds tend to have high melting and boiling points, are solids at room temperature, and conduct electricity, whereas covalent compounds often have low melting and boiling points and do not conduct electricity.
What is the role of the valency of an element in determining the type of bond it forms?
The valency of an element determines the number of bonds an atom forms when it reacts, influencing whether an ionic or covalent bond is formed.
How do σ (sigma) bonds and π (pi) bonds differ in terms of orbital overlap?
σ bonds are formed by the end-on overlap of orbitals, while π bonds are formed by the sideways overlap of p-orbitals.
What is the significance of the Octet Rule in determining the type of bond formed?
The Octet Rule states that atoms tend to reach an electronic arrangement with eight electrons in their outermost energy level, influencing whether an ionic or covalent bond is formed.
What type of bond is formed when there is an electronegativity difference of 2.1
Ionic
What is the difference between bond pairs and lone pairs in covalent bonding?
Bond pairs are electrons shared in a covalent bond, while lone pairs are electrons not involved in bonding.
What is a characteristic of polar covalent bonds?
In a polar covalent bond, electrons are unequally shared between two atoms.
Define electronegativity?
the relative attraction of an atom for the shared pair of electrons in a covalent bond.
Which type of bond is formed when electrons are shared unequally between two atoms?
Polar covalent bond
What is the tendency of atoms to reach an electronic arrangement with eight electrons in their outermost energy level?
The Octet Rule
What is the term for the number of bonds an atom of an element forms when it reacts?
Valency
What is a characteristic of covalent compounds that distinguishes them from ionic compounds?

What is the term for electrons that are not involved in bonding?
Lone pairs
What is the term for a charged atom or group of atoms?
