13 Questions
What is the primary goal of atoms during bonding according to the Octet Rule?
To reach an electronic arrangement with eight electrons in their outermost energy level
What is the characteristic of ionic compounds in terms of their physical state at room temperature?
They are mostly solids at room temperature
What is the reason why covalent substances do not conduct electricity when molten or in solution?
They do not break up to form ions
What type of bond is formed by the end-on overlap of orbitals?
σ (sigma) bond
What is the term for electrons that are shared in a covalent bond?
Bond pairs
What is the characteristic of covalent compounds in terms of their melting and boiling points?
They have low melting and boiling points
What is the term for a bond where electrons are unequally shared between two atoms?
Polar covalent bond
What is the term for atoms that have gained or lost electrons to form ions?
Ions
What is the primary difference between the outermost energy level of an atom in an ionic bond and an atom in a covalent bond?
The arrangement of electrons with eight electrons
Which type of bond is responsible for the high melting and boiling points of ionic compounds?
Electrostatic force of attraction
What is the reason why ionic compounds tend to dissolve readily in water?
They break up to form ions
What is the term for the number of bonds an atom of an element forms when it reacts?
Valency
What is electronegativity ?
the relative attraction of an atom for the shared pair of electrons in a covalent bond.
Test your understanding of chemical bonding, including the Octet Rule, valency, ions, and the electrostatic forces between oppositely charged ions that form ionic bonds.
