5.1 Chemical Bonding, Ionic and covalent bonds
Chemical Bonding: Ionic and Covalent Bonds
Discover how atoms form ionic and covalent bonds through electron transfer and sharing, and explore the unique properties of the compounds they create.
What You'll Learn
Atoms bond to achieve a stable outer electron shell arrangement.
Ionic bonds form through electron transfer between metals and nonmetals.
Covalent bonds form when two nonmetal atoms share their electrons.
Ionic and covalent compounds have distinct melting points and conductivity.
What You'll Practice
1
Students identify ionic and covalent bonds using the metal-nonmetal rule.
2
Practice questions test understanding of ions, cations, and anions formed.
3
Learners compare compound properties like melting point and electrical conductivity.
Why This Matters
Understanding ionic and covalent bonds is essential for explaining how all chemical compounds form and behave in the natural and physical world.
