How do we give names for ionic compounds and to covalent compounds?
How do we give names for ionic compounds and to covalent compounds?
For binary compounds, give the name of the first atom in the compound, then the Greek prefix for the number of the second atom. End the second atom with -ide. Name an ionic compound by the cation followed by the anion. First of all, to name a covalent compound, it helps to know what a covalent compound is.
What are the 4 rules for naming 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 is the naming different for ionic and covalent compounds?
If the first element you “see” in the compound is found on the left side of the periodic table (i.e. left of the metalloid staircase), it is a metal and the compound is “ionic.” When naming ionic compounds, we never indicate the ratio of component elements in the name – that is for covalent compounds only.
How do you name compounds with ionic compounds?
Ionic compounds are named by stating the cation first, followed by the anion. Positive and negative charges must balance. Some anions have multiple forms and are named accordingly with the use of roman numerals in parentheses.
How do you name a covalent compound?
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 are the 10 prefixes used for naming covalent compounds?
| prefix | number indicated |
|---|---|
| hepta- | 7 |
| octa- | 8 |
| nona- | 9 |
| deca- | 10 |
What are the rules for ionic and covalent compounds?
Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.
How is naming covalent compounds?
NAMING COVALENT COMPOUNDS. Naming binary (two-element) covalent compounds is similar to naming simple ionic compounds. The first element in the formula is simply listed using the name of the element. The second element is named by taking the stem of the element name and adding the suffix -ide.
What is the rule for naming compounds?
Molecular compounds are named with the first element first and then the second element by using the stem of the element name plus the suffix -ide. Numerical prefixes are used to specify the number of atoms in a molecule.
