Atoms, Bonds, and Water Flashcards
1
Q
What are three types of chemical bonds?
A
Covalent, ionic and hydrogen
2
Q
What is a covalent bond?
A
When atoms share electrons
3
Q
What does the polarity of water allow for?
A
- The ability to dissolve ionic compounds to form “hydration shells”
- The dissolving of uncharged polar molecules
- A high reactivity with transition metals/atoms
4
Q
How do Van der Waals interactions arise?
A
Van der Waals interactions arise from locally induced dipoles between atoms in very close proximity
5
Q
How do hydrogen bonds arise?
A
Due to the partial charge interacctions between polar molecules
H - O F S N

Q
What is pH?
A
The measure of a proton concentration
