Question

part vi: name the following covalent compounds containing all nonmetals. remember to use prefixes.
part vii: write the formula for the following compounds.

Explanation:

• For naming covalent compounds:
• The prefixes indicate the number of atoms of each element. For example, “mono -” is 1, “di -” is 2, “tri -” is 3, “tetra -” is 4, “penta -” is 5, “hexa -” is 6, “hepta -” is 7, “octa -” is 8, “nona -” is 9, “deca -” is 10.
• The first element in the formula is named with the element name and the prefix (except when there is only one atom, “mono -” is usually omitted for the first element). The second element is named with the prefix and the root of the element name plus “-ide”.
• For writing formulas from names:
• The prefixes are converted to the corresponding number of atoms. The first part of the name (before the second element name) gives the first element in the formula, and the second part (with “-ide” removed) gives the second element.

Answer:

PART VI:

• \(P_4O_{10}\): Tetraphosphorus decoxide
• \(Cl_2O_7\): Dichlorine heptoxide
• \(PF_3\): Phosphorus trifluoride
• \(BI_3\): Boron triiodide
• \(N_2O\): Dinitrogen monoxide
• \(SO_2\): Sulfur dioxide

PART VII:

• Carbon monoxide: \(CO\)
• Sulfur trioxide: \(SO_3\)
• Diphosphorus trioxide: \(P_2O_3\)
• Sulfur hexafluoride: \(SF_6\)
• Silicon tetrachloride: \(SiCl_4\)
• Nitrogen monoxide: \(NO\)
