FLASHCARD QUESTION
Front
What is a polar covalent bond?
Back
A polar covalent bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms, leading to a partial positive charge on one atom and a partial negative charge on the other.

FLASHCARD QUESTION
Front
What is an electronegativity difference?
Back
Electronegativity difference is the measure of the tendency of an atom to attract a bonding pair of electrons. It helps determine the type of bond formed between atoms.

FLASHCARD QUESTION
Front
What electronegativity difference indicates a polar covalent bond?
Back
An electronegativity difference between 0.4 and 1.7 typically indicates a polar covalent bond.
5.
FLASHCARD QUESTION
Front
What type of bond is formed between two atoms with an electronegativity difference of 0?
Back
A nonpolar covalent bond is formed when the electronegativity difference is 0, indicating equal sharing of electrons.
6.
FLASHCARD QUESTION
Front
What type of bond is formed between atoms with a high electronegativity difference (greater than 1.7)?
Back
An ionic bond is formed when the electronegativity difference is greater than 1.7, resulting in the transfer of electrons from one atom to another.

FLASHCARD QUESTION
Front
What is the overall polarity of water (H2O)?
Back
Water is a polar molecule due to its bent shape and the difference in electronegativity between hydrogen and oxygen.
