Understanding Ionic and Covalent Bonds
What Are Ionic Bonds?
Ionic bonds are a type of chemical bond formed when one atom donates electrons to another, resulting in the formation of ions. These bonds are typically found between metal and non-metal elements. The metal atom loses electrons to become a positively charged ion (cation), while the non-metal gains electrons to become a negatively charged ion (anion). The electrostatic attraction between these oppositely charged ions holds them together in an ionic compound.
Key Characteristics of Ionic Bonds:
- Formed between metals and non-metals
- Involve transfer of electrons
- Create ions with full outer electron shells
- Usually form crystalline solids
- Have high melting and boiling points
- Conduct electricity when molten or dissolved in water
What Are Covalent Bonds?
Covalent bonds involve the sharing of electron pairs between atoms. These bonds are common among non-metal elements. Instead of transferring electrons, atoms share them to achieve a stable electron configuration, often reaching the octet rule (eight electrons in outer shell).
Key Characteristics of Covalent Bonds:
- Formed between non-metal atoms
- Involve sharing of electrons
- Result in molecules with shared electron pairs
- Can be single, double, or triple bonds
- Usually exist as liquids, gases, or low-melting solids
- Do not conduct electricity in pure form

Frequently Asked Questions
What is the main difference between ionic and covalent bonds?
Ionic bonds involve the transfer of electrons between atoms, resulting in positive and negative ions, while covalent bonds involve the sharing of electrons between atoms.
How do ionic bonds form between atoms?
Ionic bonds form when one atom loses electrons to become a positive ion (cation) and another gains electrons to become a negative ion (anion), and these oppositely charged ions are attracted to each other.
What types of elements typically form covalent bonds?
Nonmetal elements usually form covalent bonds because they share electrons to achieve a full outer shell.
Why do ionic compounds tend to have high melting points?
Because ionic bonds are strong electrostatic attractions between ions, they require a lot of energy to break, resulting in high melting points for ionic compounds.
Can a molecule be both ionic and covalent? If so, how?
Yes, some compounds have both ionic and covalent characteristics, such as polyatomic ions bonded covalently within the ion, and these ions bonded ionically to other ions in the compound.
What is a common example of an ionic compound and a covalent molecule?
Sodium chloride (NaCl) is a common example of an ionic compound, while water (H₂O) is a common covalent molecule.
How can you distinguish between ionic and covalent bonds in a chemical formula?
Ionic bonds are often between metals and nonmetals and can be indicated by the presence of metal and nonmetal elements, whereas covalent bonds occur between nonmetals and are usually represented by shared electron pairs in the formula.
