Fill in the following table. # of bonded atoms to central atom # of lone pairs on Molecular shape Bond angle 120° 120° central atom Trigonal pyramidal 180° tetrahedral bent 104.5°
The correct answer and explanation is:
Here are the correct answers for the ionic/covalent classification and molecular names:
- E) K₃PO₄ – Potassium phosphate (Ionic)
- F) P₂O₅ – Diphosphorus pentoxide (Covalent)
- G) ZnBr₂ – Zinc bromide (Ionic)
- H) Pb(CN)₂ – Lead(II) cyanide (Ionic)
- D) N₂O – Dinitrogen monoxide (Covalent)
Explanation (300 words):
Chemical compounds are classified as either ionic or covalent based on the type of bonding between atoms.
- Ionic compounds consist of a metal and a non-metal. Metals donate electrons to non-metals, forming positive and negative ions held together by electrostatic attraction. Examples:
- K₃PO₄ (Potassium phosphate) contains potassium (K⁺) and phosphate (PO₄³⁻) ions, making it ionic.
- ZnBr₂ (Zinc bromide) consists of Zn²⁺ and Br⁻ ions, forming an ionic bond.
- Pb(CN)₂ (Lead(II) cyanide) contains the Pb²⁺ ion and cyanide (CN⁻) anions, making it ionic.
- Covalent compounds involve the sharing of electrons between non-metal atoms. Examples:
- P₂O₅ (Diphosphorus pentoxide) involves phosphorus (P) and oxygen (O) atoms that share electrons, making it covalent.
- N₂O (Dinitrogen monoxide) consists of nitrogen and oxygen, which are both non-metals that share electrons.
