Back

bond type where atoms share electrons (can result in polarity/difference in electronegatives). can be single, double, or triple

ionic bond, results in...

Back

- electrons are transferred from one atom to another, metal-nonmetal

- results in positively and negatively charged ions that attract (ex Na+Cl- for salt)

hydrogen bond

Back

weak bond interaction between the negative and positive regions of two separate molecules (ex. in water)

6.

FLASHCARD QUESTION

Front

cohesion

Back

when two of the same molecules form hydrogen bonds with each other (ex water and water)

7.

FLASHCARD QUESTION

Front

adhesion

Back

when two different molecules form hydrogen bonds with each other (ex. water defies gravity when moving up xylem vessels for nutrient transport in capillary action)
