Ionic bonds are basically formed between a metal and a non-metal, or for that matter, a cation and an anion. While in a covalent bond, electron pairs are shared among atoms.
Related questions to: Which Pair Of Elements Is Most Likely To Form An Ionic Bond?
Which pair of elements are likely to form an ionic compound?
Ionic compounds usually form between metallic and non-metallic elements. For instance, the metal calcium (Ca) and the nonmetal chlorine (Cl) combine together to form the ionic compound calcium chloride (CaCl2).
Which pair of ions can form an ionic bond with each other and why?
Lithium and bromide ions can form an ionic bond with each other because due to the presence of unlike charges that attract each other. So they form an ionic compound through ionic bonds.
What pair of elements are capable of producing an ionic bond?
If the pair has a metal and a non-metal, then they are most capable to form ionic bonds. These types of ionic compounds are made of monatomic cations and anions.
Which pair of elements is most likely to form ionic bonds according to Brainly?
Answer: The pair of elements that form an ionic bond will be, barium and chlorine. Explanation: Ionic bond is defined as the bond that is formed by the complete transfer of electrons from one atom to the other.

These are some examples of ionic bonds:
LiCl – Lithium Chloride.
NaF – Sodium Fluoride.
NaBr – Sodium Bromide
LiBr – Lithium Bromide.
LiI – Lithium Iodide.
NaCl – Sodium Chloride.
NaI – Sodium Iodide.
LiF – Lithium Fluoride.
What is an ionic bond?
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions.
In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
What will be the best example of an ionic compound?
Ionic Compounds are very balanced. One such example of an ionic compound is table salt. Sodium and chlorine ions come together to form sodium chloride or NaCl. Each sodium cation bonds with each chloride anion.
Which element is the most electronegative?
Electronegativity varies in a predictable way across the periodic table. It increases from bottom to top in groups and from left to right across periods.
So going by the table, fluorine is the most electronegative element while francium is one of the least electronegative elements present.
Can Oxygen form ionic bonds?
An oxygen molecule (O2) is an excellent example of a molecule with a covalent bond. Ionic bonds occur when electrons are donated from one atom to another. Table salt (NaCl) is a common example of a compound with an ionic bond.
Is sodium metal or non-metal?
Sodium is a member of the alkali metal group, denoted by the symbol Na. It is a silver-colored metal and soft in texture with low density. Although pure sodium is not present naturally on earth as it has extremely reactive metallic properties.
What are the characteristics of an ionic compound?
The main characteristic of an ionic compound is that all these ionic compounds form crystals. Cations are usually metal atoms and anions are either nonmetals or polyatomic ions, that is, ions with more than one atom.
Also, ionic compounds have high melting as well as boiling points. These compounds are very hard and very brittle too. Of course, there are exceptions.
Which elements form covalent bonds?
Covalent bonds generally tend to occur with nonmetal elements of the periodic table. A very common example is water, which is a molecule formed with hydrogen and oxygen linked by covalent bonds. Such elements are considered to be covalent.
There are other elements that can form covalent bonds such as carbon, nitrogen, as well as fluorine among others.
How is HCl a covalent compound while NaCl is an ionic compound?
(A) Both hydrogen and chlorine are non-metals and the bond formed between two non-metals is a covalent bond. So hydrogen and chlorine will form share electrons with each other and the resulting compound HCl will be a covalent compound.
(B) Sodium is metal while chlorine is non-metal, so they will transfer electrons to form an ionic bond, resulting in NaCl which is an ionic compound.
Give some examples of elements that will form a covalent bond with each other?
The best examples for covalent bonds are between diatomic elements such as hydrogen, oxygen, fluorine, etc. Bonds between elements with small differences in electronegativity are also considered highly covalent.
For the most part, non-metals (excluding Nobel gases) are the most likely to form covalent bonds.
How does the element Calcium follow the octet rule?
Calcium or Ca is located in group 2 of the periodic table, so this implies that its outermost shell has two electrons. So to achieve a complete octet, calcium must lose these two outermost electrons, also called valence electrons.
So calcium reacts with non-metals(as it itself is metal) to form ionic compounds.
Are ionic bonds present in our bodies too?
Of course. Our cells are made up of many salts. Since ionic bonds are usually found in dry forms such as salts and are also soluble in water, our cells are filled with such ionic compounds.
Explain the bond in Na2Co3?
Since sodium is metal and carbonate is non-metal, the bond between them is an ionic bond. Every compound that is formed between a metal atom and a non-metal atom is ionic in nature, while every compound formed between non-metal atoms is covalent in nature by default.
What do we mean by ionic bonds?
By definition, an ionic bond is when a positively charged ion forms a bond with a negatively charged ion, or when there is a transfer of electrons between atoms, then it is called an ionic bond. A great and common example of an ionic bond is the chemical compound Sodium Chloride.
What happens to electrons in a covalent bond?
Covalent bonding occurs when pairs of electrons are shared by atoms. This is done so that atoms can have more stability, which can only be gained by forming a full electron octet.
So if they share their outermost electrons, called valence electrons, atoms can complete their shells and gain stability, which every atom aspires for.
Why role does lattice energy play in the formation of an ionic bond?
Lattice energy for an ionic compound is the energy required to separate one mole of a compound into its gas-phase ions. It is present in ionic bonds and this energy is more for ions that contain higher charges and have shorter distances between their ions.
What type of bond is considered the strongest?
Covalent bonds are considered the strongest bonds in nature as they are formed by sharing electrons of atoms. They are the strongest among all kinds of chemical bonds.
