Binary Compounds

Everyone needs to have a basic knowledge of compounds and other chemicals; it’s for our safety. A lot of chemicals that we see daily are quite reactive and need to be handled carefully. The study of chemistry teaches which chemical compounds are not harmful to be used and which one needs to be stored far away from the reach of children. This article briefs you about what is a binary compound, along with the binary ionic compound list. These words may sound gibberish to you at first, but soon you are going to recognize them in your daily life. So why not start learning about them from now?!


Before we go any further, we need to talk about why binary compounds and why they are so crucial in the field of chemistry. Binary compounds are the ones that contain precisely two kinds of different elements. The word Binary comes from the word Bi which means two. On the other hand, these compounds show strong chemical bonds such as metallic, ionic, and covalent. 


Binary Ionic Compounds List

The importance of binary compounds was raised to the whole new level after the discovery of Ionic compounds. Most of the ionic compounds that we have in our periodic table are two-element compounds where one of the compounds is metal, and the other one is non-metal. In addition to this, binary ionic compounds start from two compounds, but they can become extremely complex in terms of properties and can form polyatomic ionic compounds. 


Given below is a binary ionic compounds list, this will help you understand where these compounds are being used and how. 

  • NaCl, where Na⁺ is positive and Cl⁻ is negative, makes it Sodium Chloride.

  • Li₃N, here Li is positive, and N₋₃ is negative, this formula is used to show Lithium Nitride. 

  • Magnesium Oxide can be written as MgO, where Mg₂₊ is positive and O₂₋O-2 is negative. 

These are some of your compounds that come in binary ionic compounds list.


Difference Between Binary Acids And Binary Compounds

A lot of students get confused when the question asks them to name binary acids. First, we need to clear out the definition of binary acids; well, it will be much easier if we take an example. Let’s look at three compounds, mainly hydriodic acid, hydrofluoric acid, and hydrobromic acid. Now here you noticed one thing. 


All the compounds have one element in common, and that is your hydrogen atom. Still, on the other hand, all the remaining three compounds are non-metal, these are iodine, fluorine, and bromine, which makes them binary acids. These acids have one hydrogen element and a nonmetal element. All three compounds that we have written in the example are bonded together, a hydrogen element from a non-metal.


The other difference between binary acids and binary compounds is that the strength of binary acids depends on the bond between the hydrogen atom and the other given element. The weaker is the bond; the stronger will be the acid. 


Each binary acid that we have in chemistry starts with the prefix “hydro,” followed by the name of other elements, and in the postfix, we add “-ic.” Thus, if you a binary acid from two given elements, Hydrogen, and chlorine, then you will name that acid as hydro+chlo+ric acid. 


Naming Binary Compounds

Now we know what a binary compound is, and we can find if the given compound is binary or not, but the other problem with chemistry is naming the compound. So here, we are going to show you steps on how to name a binary compound. There are some points that you need to know before you go and name binary compounds.

First comes the cation, and then anion follows the order you need to follow for binary compounds.


When you are using cation that has the fixed oxidation state, you can take out the name directly from the periodic table. 


The name of anion will come up by root of the element’s name with the addition of the suffix “-ide.”


Examples Of Binary Compounds

Now let’s try to name binary compounds using some examples. All the examples we are going to show consists of only one charge, and it includes both the cation and anion in the given formula. 


Example: 1 Write the name of the given formula KCl


The first part of the name will come from the first element in the given formula. Here we have “K,“ which is the chemical symbol of Potassium. 


The postfix is the root of the first name of the second symbol, which is “Cl” and the name of the element is Chloride.


Now add the postfix after taking root from the second symbol add “-ide” and you will have your complete name.


As a result, we have had KCl = Potassium Chloride.

FAQ (Frequently Asked Questions)

Can we put Sodium Chloride in a Binary Compound List and How do we Use it?

Yes, Sodium Chloride is a binary ionic compound that consists of Sodium as cation and Chloride as an anion. The solid Sodium Chloride is present in white crystalline form in which Na ion is surrounded in a shape of octahedral geometry by six chloride ions. The NaCl is quite common in your daily life, you can find it in your kitchen as it is your table salt which is widely used in adding flavor while preparing food.

How do we Name Type II Binary Ionic Compounds?

The second type of binary compounds is not from the metal which is present in the first and the second group of the periodic table, to get the name of these binary compounds you need to follow some rules


The cation of the compound will always become in the prefix and it has to be the full name.


After that, we have to put the Roman numeral to show the oxidation number for the metal cation.


Now in the suffix, the anion drops the “-ine” and adds “ide”


Example: CuCl = copper(I) chloride.
