Types of Chemical Bonds

What type of bond is formed when hydrogen and oxygen atoms share electrons to create hydrogen peroxide (H2O2)?

Which of the following best describes the primary interaction that causes individual water molecules to orient towards one another?

Which statement correctly differentiates between ionic and covalent bonds?

When calcium (Ca++) and chloride (Cl−) ions interact, they form what type of bond?

Within a single molecule of water (H2O), what type of bond holds the hydrogen and oxygen atoms together?

Types of Chemical Bonds

Covalent bonds: Atoms share electrons to form bonds. This is how hydrogen and oxygen atoms form hydrogen peroxide (H₂O₂).
Hydrogen bonds: Bonds form between individual water molecules due to the orientation of water molecules.
Ionic bonds: Oppositely charged atoms (ions) attract each other to form bonds. Calcium (Ca²⁺) and chloride (Cl⁻) ions bond ionically.
Peptide bonds: These bonds form proteins. They are not relevant to the examples in the questions.

Distinguishing Ionic and Covalent Bonds

Ionic bonds form between atoms with opposing charges—one positively charged and one negatively charged
Covalent bonds form when atoms share electrons.

Water Molecules and Bonds

Within a single water molecule, hydrogen and oxygen atoms are held together by polar covalent bonds.
Hydrogen bonds form between different water molecules due to the polarity of the water molecules.

Ionic Bonding Examples

Calcium (Ca²⁺) and chloride (Cl⁻) ions form ionic bonds.
Lithium (Li⁺) can also participate in ionic bonding.

Hydrogen Bonds

Hydrogen bonds are individually weak bonds, but collectively they are significant in the structure and function of water.
