List three main types of chemical bonds, and give an example of each.

Verified step by step guidance

1. Identify the three main types of chemical bonds commonly discussed in microbiology and chemistry: ionic bonds, covalent bonds, and hydrogen bonds.
2. Explain that an ionic bond is formed when one atom donates an electron to another, resulting in oppositely charged ions that attract each other. An example is the bond between sodium (Na) and chloride (Cl) in sodium chloride (NaCl).
3. Describe a covalent bond as a bond where atoms share one or more pairs of electrons to achieve stability. An example is the bond between two hydrogen atoms (H) in a hydrogen molecule (H\_2).
4. Define a hydrogen bond as a weak interaction between a hydrogen atom covalently bonded to an electronegative atom (like oxygen or nitrogen) and another electronegative atom. An example is the hydrogen bonding between water molecules (H\_2O).
5. Summarize by listing each bond type alongside its example to clearly distinguish them.

Key Concepts

Ionic Bonds

Ionic bonds form when one atom transfers electrons to another, creating positively and negatively charged ions that attract each other. An example is sodium chloride (NaCl), where sodium donates an electron to chlorine.

Covalent Bonds

Covalent bonds occur when atoms share one or more pairs of electrons to achieve stability. Water (H2O) is an example, where oxygen shares electrons with hydrogen atoms.

Hydrogen Bonds

Hydrogen bonds are weak attractions between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom. They are important in water molecules, where hydrogen bonds link different water molecules together.
