Name the compounds. Spelling counts
BiBr3
NO3
The Correct Answer and Explanation is :
The names of the compounds are:
- BiBr₃ – Bismuth(III) bromide
- NO₃ – Nitrogen trioxide (if referring to the molecular compound) or Nitrate (if referring to the polyatomic ion)
Explanation:
1. Naming BiBr₃ (Bismuth(III) bromide)
- Bismuth (Bi) is a metal and belongs to Group 15 of the periodic table.
- Bromine (Br) is a nonmetal and belongs to Group 17 (halogens).
- Since bismuth can have multiple oxidation states (+3 and +5), we need to specify which oxidation state it has in this compound.
- Bromine, as a halogen, usually forms a -1 charge.
- Since there are three bromide (Br⁻) ions, the total negative charge is -3.
- To balance this charge, bismuth must have a +3 charge.
- We indicate this with Roman numerals in parentheses: Bismuth(III) bromide.
2. Naming NO₃
- This formula can have two different meanings:
- As a molecular compound (NO₃): It follows the covalent naming rules.
- Nitrogen (N) and oxygen (O) are both nonmetals, so we use prefixes.
- “Tri-” means three oxygens, so the name is Nitrogen trioxide.
- As a polyatomic ion (NO₃⁻): It is called Nitrate.
- This is a common polyatomic ion with a -1 charge.
- It is found in many compounds, such as sodium nitrate (NaNO₃).
