What are the steps rules for naming molecular covalent compounds?
Rules for naming simple covalent compounds:
- Name the non-metal furthest to the left on the periodic table by its elemental name.
- Name the other non-metal by its elemental name and an -ide ending.
- Use the prefixes mono-, di-, tri-…. to indicate the number of that element in the molecule.
How do you write the names of covalent compounds?
Rules for Naming Covalent Compounds
- First, name the nonmetal furthest to the left and bottom of the periodic table by its element name.
- Second, name the other nonmetal by its element name, but shorten its name and add an -ide ending.
- Add prefixes (mono-, di-, tri-, etc.)
What is the first step in naming covalent compounds?
First, give the name of the first atom in the compound. Then give the Greek prefix for the number of the second atom. Then name the second atom and end it with -ide.
What are the naming rules for covalent compounds and acids?
Naming Acids, Oxyacids and Their Salts
- If the anion does not contain oxygen, then the acid is named with the prefix hydro- and the suffix -ic.
- If there are only two members in the same series, then the anion with the least number of oxygens ends in -ite, and the anion with the most ends in -ate.
Are molecular and covalent compounds the same?
The terms covalent and molecular are often used interchangeably to describe the same type of substance. However, there is a distinction between the two. The term covalent refers to a type of bonding in which pairs of valence electrons are shared by two atoms. Molecular compounds are a type of covalent compound.
How do you name a compound with 3 elements?
If the compound contains three elements one of which is oxygen then the compound name will end in –ate or –ite, eg Calcium carbonate contains calcium, carbon and oxygen….Rule three.

What are the basic rules for naming elements?
Certain rules apply to the usage of element names:
- Element names are not proper nouns.
- Element symbols are one- or two-letter symbols.
- Halogen element names have an -ine ending.
- Nobel gas names end with -on.
- Newly discovered elements may be named for a person, place, mythological reference, property, or mineral.
What do you need to name a covalent compound?
To name a covalent compound, you need the molecular formula, knowledge of the prefixes used for naming, and a way to look up the name of an element given its atomic symbol. With this information in hand, you can follow the naming scheme for covalent compounds:
What makes a ionic compound a covalent compound?
Remember, ionic compounds are metal combined with a non-metal. A covalent compound is the combination of non-metals. 1. Name the non-metal furthest to the left on the periodic table by its elemental name.
What are the rules for naming ionic compounds?
The rule said that for molecular compounds that only contained non-metals we use (# prefix) first compound + (# prefix) second compound, but in the quiz it wants carbon monoxide instead of monocarbon monoxide, and I’m just confused when the leading element gets the prefix, when it doesn’t, and what rules there were surrounding that?
How to write the name of a compound?
Write the name of the compound. Binary compounds of the elements with oxygen are generally named as “element oxide,” with prefixes that indicate the number of atoms of each element per formula unit. For example, CO is carbon monoxide. The only exception is binary compounds of oxygen with fluorine, which are named as oxygen fluorides.
