Chemical Bonds: Ionic and Covalent
Ysci・2 minutes read
Atoms bond to achieve stability by filling their outer shell with electrons using ionic or covalent bonds based on electron transfer or sharing, respectively. Ionic bonds form through electron transfer between metals and non-metals, creating oppositely charged ions that attract each other to create compounds like sodium chloride, while covalent bonds involve electron sharing between non-metals with similar electronegativity values, leading to the formation of molecules like H2 and HCl with differing degrees of electron sharing.
Insights
- Atoms bond to reach stability by completing their outer shell, typically seeking eight electrons (octet rule) for stability.
- Ionic bonds involve electron transfer between metals and non-metals, resulting in oppositely charged ions that attract each other, forming compounds such as sodium chloride.

Recent questions
What is the octet rule?
Atoms prefer bonding to achieve stability by filling their outermost shell with electrons, following the octet rule where most atoms require eight electrons in their valence shell.
How do ionic bonds form?
Ionic bonds form through electron transfer between metals and non-metals, creating oppositely charged ions that attract each other to create compounds like sodium chloride.
What are covalent bonds?
Covalent bonds occur when atoms share electrons, with non-metals forming these bonds based on their similar electronegativity values, leading to the creation of molecules like H2 and HCl with varying degrees of electron sharing.
