chemical formula
Step1: Determine the ions or elements
For ionic compounds (first part), identify the cation and anion. For example, rubidium (Rb⁺) and oxide (O²⁻). For covalent compounds (second part), use prefixes to determine the number of atoms. For example, "dihydrogen" means 2 H atoms.
Step2: Apply charge balance (for ionic) or prefix - atom number correlation (for covalent)
- Ionic compounds:
- Rubidium oxide: Rb⁺ and O²⁻. To balance charges, we need 2 Rb⁺ for 1 O²⁻. Formula: $Rb_{2}O$.
- Aluminum chloride: Al³⁺ and Cl⁻. Need 3 Cl⁻ for 1 Al³⁺. Formula: $AlCl_{3}$.
- Magnesium sulfide: Mg²⁺ and S²⁻. 1:1 ratio. Formula: $MgS$.
- Barium nitride: Ba²⁺ and N³⁻. To balance, 3 Ba²⁺ (total + 6) and 2 N³⁻ (total - 6). Formula: $Ba_{3}N_{2}$.
- Zinc oxide: Zn²⁺ and O²⁻. 1:1 ratio. Formula: $ZnO$.
- Copper (II) chloride: Cu²⁺ and Cl⁻. 1 Cu²⁺ and 2 Cl⁻. Formula: $CuCl_{2}$.
- Titanium (IV) oxide: Ti⁴⁺ and O²⁻. 1 Ti⁴⁺ and 2 O²⁻. Formula: $TiO_{2}$.
- Iron (II) bromide: Fe²⁺ and Br⁻. 1 Fe²⁺ and 2 Br⁻. Formula: $FeBr_{2}$.
- Mercury (I) chloride: Hg₂²⁺ (mercurous ion) and Cl⁻. 1 Hg₂²⁺ and 2 Cl⁻. Formula: $Hg_{2}Cl_{2}$.
- Palladium (III) oxide: Pd³⁺ and O²⁻. 2 Pd³⁺ (total + 6) and 3 O²⁻ (total - 6). Formula: $Pd_{2}O_{3}$.
- Covalent compounds:
- Dihydrogen monoxide: "dihydrogen" = 2 H, "mono - oxide" = 1 O. Formula: $H_{2}O$.
- Carbon dioxide: "di - oxide" = 2 O, 1 C. Formula: $CO_{2}$.
- Trisilicon heptahydride: "tri - silicon" = 3 Si, "hepta - hydride" = 7 H. Formula: $Si_{3}H_{7}$.
- Dinitrogen monoxide: "di - nitrogen" = 2 N, "mono - oxide" = 1 O. Formula: $N_{2}O$.
- Phosphorous pentachloride: "penta - chloride" = 5 Cl, 1 P. Formula: $PCl_{5}$.
- Dichlorine heptoxide: "di - chlorine" = 2 Cl, "hepta - oxide" = 7 O. Formula: $Cl_{2}O_{7}$.
- Xenon difluoride: "di - fluoride" = 2 F, 1 Xe. Formula: $XeF_{2}$.
- Bromine pentafluoride: "penta - fluoride" = 5 F, 1 Br. Formula: $BrF_{5}$.
- Diphosphorous pentoxide: "di - phosphorous" = 2 P, "penta - oxide" = 5 O. Formula: $P_{2}O_{5}$.
- Boron trifluoride: "tri - fluoride" = 3 F, 1 B. Formula: $BF_{3}$.
