AnswersDriveMethod 1 Basic Ionic Compounds
- Write down the formula of the ionic compound.
- Write the name of the metal, or the cation.This is the positively charged ion in the compound, and it is always written first in ionic compound formulas.
- Write the name of the nonmetal, or the anion, with the "-ide" ending.
- Combine the names.

How do you name a compound?
Rules for Naming Molecular Compounds:
- Remove the ending of the second element, and add “ide” just like in ionic compounds.
- When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound.
- If there is only one of the first element, you can drop the prefix.

What are ionic compounds give examples?
Table salt is an example of an ionic compound. Sodium and chlorine ions come together to form sodium chloride, or NaCl. The sodium atom in this compound loses an electron to become Na+, while the chlorine atom gains an electron to become Cl-.

How do you name a binary acid?
Rules for naming binary acids:
- As the pure compound (ie - in the gaseous or liquid state), start with 'hydrogen' follow by the anion name ending in '-ide'.
- As aqueous acid solutions, start with 'hydro-'. change the anion name to end with '-ic'. add the word 'acid' at the end.

What is an Iupac name?
In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a systematic method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book).
5
Is ionic bonding between a metal and a nonmetal?
Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
6
How are the formulas of acids determined?
To write the formula for a binary molecular compound, write the symbols for the elements and use the prefixes to determine the subscripts. An acid is a combination of a monatomic or polyatomic anion with sufficient hydrogen atoms to make the compound electrically neutral.
7
How do you name a salt?
The first part of the name comes from the metal in the metal oxide, hydroxide or carbonate. The second part of the name comes from the acid used to make it. The names of salts made from hydrochloric acid end in chloride, while the names of salts made from sulphuric acid end in sulphate.

How do you create a chemical formula?
Part 1 Writing Chemical Formulas of Covalent Compounds
- Memorize the prefixes for number of atoms.
- Write the chemical symbol for the first element.
- Add the number of atoms as a subscript.
- Write the chemical symbol for the second element.
- Add the number of atoms present as a subscript.
- Practice with some examples.

How do you name an ionic compound?
Method 1 Basic Ionic Compounds
- Write down the formula of the ionic compound.
- Write the name of the metal, or the cation.This is the positively charged ion in the compound, and it is always written first in ionic compound formulas.
- Write the name of the nonmetal, or the anion, with the "-ide" ending.
- Combine the names.
10
What compounds use prefixes in their names?
However, simple covalent compounds are generally named by using prefixes to indicate how many atoms of each element are shown in the formula. Also, the ending of the last (most negative) element is changed to -ide. The prefixes used are mono-, di-, tri-, tetra-, penta-, hexa-, and so forth.
11
What is the molecular compound?
Binary molecular compounds are composed of only two elements. Molecular compounds are more difficult to name because the atoms combine through covalent and not ionic bonds. Therefore we cannot use the electrical neutrality rule for these compounds. Most molecular compounds are made from nonmetals.
12
What are the rules for naming an ionic compound?
When naming ionic compounds containing polyatomic ions, we follow the same general rule:
- Name the cation first; this can be a metal or a polyatomic cation.
- Name the anion second; this can be a nonmetal, and if this is the case, change the suffix of the nonmetal to '-ide.'
13
How do you know if a compound is ionic or covalent?
There is a couple different ways to determine if a bond is ionic or covalent. By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.
14
How do you name covalent compounds?
Method 2 Naming Basic Binary Compounds
- Name the first element in the compound.
- Write the Greek prefix for the number of the second atom.
- Name the second atom and end it with "-ide."
- Add a Greek prefix at the beginning if there is more than one of the first atom.
- Put it all together.
15
How do you write a chemical formula?
Ionic compounds are neutral compounds made of positive cations and negative anions. Writing the chemical formula for ionic compounds is fairly easy. Write the cation symbol, then the anion symbol. Find the lowest common multiple for the ions to make the compound neutral.
16
How do you name an Oxyacid?
An oxyacid with two less oxygen atoms than the (root)ic acid is named by writing hypo-, then the root of the name for the element other than hydrogen and oxygen, then -ous, and then acid. Therefore, HClO, is hypochlorous acid.
17
How do you read a chemical formula?
Note that:
- The number of atoms of each element is written as a subscript;
- When only a single atom of an element is present, the subscript is omitted.
- In the case of organic (carbon-containing) compounds, it is customary to place the symbols of the elements C, H, (and if present,) O, N in this order in the formula.
18
How do you name a transition metal compound?
Write the name of transition metal as shown on the Periodic Table. Write the name and charge for the non-metal. If you have a polyatomic ion, use the Common Ion Table to find and write the formula and charge. Use the total charge on the non-metal (or polyatomic ion) find the charge on the transition metal.
19
How do you write the name of a binary compound?
Points to remember about naming a compound from its formula
- The order for names in a binary compound is first the cation, then the anion.
- Use the name of cation with a fixed oxidation state directly from the periodic table.
- The name of the anion will be made from the root of the element's name plus the suffix "-ide."

What is a covalent compound?
A covalent compound is made when two or more nonmetal atoms bond by sharing valence electrons. The shared valence electrons between two nonmetal atoms is called a covalent bond. Covalent bonds are formed when two atoms begin sharing electrons. The electrons are attracted to the positively charged nuclei of the atoms.
