Bonding in Polyatomic Ions and Compounds | Summary and Q&A

TL;DR

Polyatomic ions are clumps of atoms held together by covalent bonds within the ion and ionic bonds between ions, resulting in a charge.

Key Insights

• 😑 Polyatomic ions are clumps of atoms connected together with a charge.
• 😑 Covalent bonds hold the atoms within the polyatomic ion together.
• 😑 Ionic bonds attract ions with opposite charges, holding polyatomic ions together in compounds.
• 😚 Polyatomic ions can gain or lose electrons to achieve a stable valence electron configuration.
• 😚 The charge of a polyatomic ion is determined by the number of electrons gained or lost.
• 😑 Polyatomic ions can have different charges depending on the elements involved.
• 😑 In compounds with polyatomic ions, both ionic and covalent bonds are present.

Transcript

let's talk about bonding in polyatomic ions and compounds that have polyatomic ions in them so a whole bunch of polyatomic ions this is just a small list of some of them but they all share one thing in common and that's that they all are a bunch of atoms connected together in a clump and that clump then has a charge okay that's what a polyatomic io...

Questions & Answers

Q: What is a polyatomic ion?

A polyatomic ion is a clump of atoms connected together with a charge. It can be made up of multiple elements.

Q: How are the atoms within a polyatomic ion held together?

The atoms within a polyatomic ion are held together by covalent bonds, where electrons are shared between the atoms.

Q: What holds the polyatomic ions together in a compound?

In compounds, polyatomic ions are held together by ionic bonds, which result from the attraction between ions with opposite charges.

Q: Why do polyatomic ions have a charge?

Polyatomic ions have a charge because in order to achieve stable electron configurations, they must either gain or lose electrons through covalent bonding.

Summary & Key Takeaways

• Polyatomic ions are groups of atoms connected together with a charge.

• Covalent bonds hold the atoms within the ion together, while ionic bonds attract opposite charges between ions.

• Polyatomic ions can gain or lose electrons to achieve a stable valence electron configuration, resulting in a charge.
