Bonds
This type of weak attraction occurs between a hydrogen atom and a highly electronegative atom.
Hydrogen Bond
What is the maximum amount of electrons that can be held in the 3rd shell?
8
This type of bonding between water molecules is responsible for cohesion and high boiling point.
Hydrogen Bonds
A solution with a pH of 3 is considered this
Acidic
This type of bond forms when one atom transfers electrons to another.
Ionic Bond
This negatively charged particle is found outside the nucleus.
This property allows water molecules to stick to each other, creating surface tension.
Cohesion
Acids release this ion in water.
H⁺ (hydrogen ion)
O₂ and N₂ are examples of molecules with this type of bond.
Nonpolar Covalent Bond
Identify the element with 12 protons and 12 neutrons.
Magnesium
True or false. Ice floats because it is less dense than liquid water.
True.
This type of solution resists changes in pH when small amounts of acid or base are added.
Buffer
Water is an example of a molecule held together by this type of bond
This particle’s number determines an element’s identity on the periodic table.
Proton
This term describes water sticking to surfaces, which along with cohesion, helps water move through plants.
Adhesion
If you add a strong acid to pure water, the concentration of H⁺ ions increases. This causes the pH to do what?
Decrease
This symbol (δ⁺ or δ⁻) shows partial charges on atoms.
Polar Covalent Bond
This isotope of oxygen has 8 protons and 10 neutrons.
Oxygen-18
If you want to raise the temperature of water, what must you do to the bonds between its molecules first?
Break hydrogen bonds
Lemon juice has a pH around 2. Which is stronger: lemon juice or vinegar (pH 3), and by how many times in H⁺ concentration?
lemon juice; 10 times stronger
