2.3- Chemical bonds Flashcards
Bio ll
What are the three types of bonds?
Nonpolar covalent, polar, and ionic bonds
What are nonpolar covalent bonds?
Bonding electrons shared equally between two atoms
What does bonding prove?
Stability
What is an ionic bond?
A bond between atoms with a large difference in electronegativity
Where are ionic bonds located on the periodic table?
Opposite sides
When are atoms the most stable?
When they have a full valence shell (octet rule)
What does equal electronegativity have?
An equal pull on an electron pair
What happens to a nonpolar covalent bond when submerged in water?
It breaks into separated atoms
What happens to an ionic bond when submerged in water?
It breaks into separate molecules
What is the difference between a high and a low electronegativity?
High=strong pull, Low=weak pull
