One of the ways is by donating or accepting electrons to complete their octet configuration. The bond formed by this kind of combination is known as an ionic bond or electrovalent bond. This kind of bond is formed when one atom gains electrons while the other atom loses electrons from its outermost level or orbit.
What pair or atoms can form an ionic bond?
You can recognize ionic compounds because they consist of a metal bonded to a nonmetal. Ionic bonds form between two atoms that have different electronegativity values. Because the ability to attract electrons is so different between the atoms, it's like one atom donates its electron to the other atom in the chemical bond.

Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons. Ions with opposite charges will attract one another creating an ionic bond. Such bonds are stronger than hydrogen bonds, but similar in strength to covalent bonds.
What are ionic bonds and how are they formed?
ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
How are ionic bonds formed step by step?
The atom losing one or more electrons becomes a cation—a positively charged ion. The atom gaining one or more electron becomes an anion—a negatively charged ion. When the transfer of electrons occurs, an electrostatic attraction between the two ions of opposite charge takes place and an ionic bond is formed.

How do you write an ion?
When writing the symbol for an ion, the one- or two-letter element symbol is written first, followed by a superscript. The superscript has the number of charges on the ion followed by a + (for positive ions or cations) or - (for negative ions or anions). Neutral atoms have a charge of zero, so no superscript is given.

Ionic Bond FAQs
Ans.3 Ionic bonds are stronger than covalent bonds due to the coulombic attraction between ions of opposite charges.
How are the constituent ions of an ionic compound held together?
In any crystal, the constituent ions of the ionic compound are held together by electrostatic forces of attraction. The stronger the forces of attraction, the higher is the lattice energy and the more stable is the compound. This electrostatic force of attraction is determined by Coulomb’s Law.

We are all quite familiar with table salt that we use to add flavour to food. We also know that chemically, table salt is sodium chloride in which sodium and chloride ions are bonded together by ionic bonds. Various factors affect the formation of these ions and consequently ionic bonding, which ultimately gives rise to ionic compounds. The factors are –
What is the term for the transfer of electrons from an electronegative element to an atom of an electronegative element
The chemical bond that is formed between 2 atoms through the transfer of one or more electrons from the electropositive or metallic element to the atom of an electronegative or non-metallic element is called an ionic or electrovalent bond .
What is the bond between calcium and oxygen?
Similarly, metal-like calcium loses two of its outermost electrons to a non-metal-like solid-state, oxygen resulting in an ionic bond between calcium and oxygen forming Calcium oxide (CaO). 1. A metal always forms the cation, whereas a non-metal always forms the anion. 2.
Why are ionic compounds brittle?
Ionic compounds are brittle – When an external force is applied to the crystals of an ionic compound, it shatters into pieces. This happens because, in the crystals of sodium chloride, the Na + ions and Cl – ions are lined up against each other in a lattice with a strong electrostatic force of attraction.
What is the conductivity of ionic compounds?
Electrical conductivity – In solid-state, ionic compounds are generally non-conductors of electricity. When heated to a temperature above their melting point, the electrostatic force of attraction between the ions breaks, and the ions become free to move. These free ions can now allow the passage of electricity. 5.
What is the ionization energy of sodium?
Consider the formation of sodium ion (Na +) from sodium atom. The ionization energy of sodium is about 500kJ / mol, which is quite low. It can easily lose electrons and get converted into a sodium ion. This ion can further take part in ionic bond formation with other anions such as Cl –, Br –.

How many valence electrons does chlorine have?
If that same hydrogen bonded to Chlorine, the hydrogen would get the two electrons it needs to be complete and the chlorine which has 7 valence electrons would get the one more to fulfil its octet. See above. Now that you can form covalent compounds we need to go over how to name these compounds.
How many electrons does hydrogen have to have to have a full valence shell?
There are several exceptions to the octet rule however: Hydrogen (H) only requires 2 electrons to have a full valence shell since it only needs to be like Helium (He).
Why do you not use the Greek prefix in ionic nomenclature?
This is because as chemists we know the number since the charge the ions take on is predictable. So to sum up the process for identifying, writing and naming compounds:
Why is it easier to lose electrons than to gain electrons?
This is because it is easier energetically for those elements to lose 1, 2, or 3 electrons than it would be for them to gain 5, 6 or 7 electrons. The gain or loss of an electron generally requires energy and once you exceed the gain or loss of 3 electrons the energy cost is simply too high for most atoms to accomplish.

It's how you can turn an exercise in answering questions into an exercise in learning. Tapping on the Help Me button will open a page with help that is specific to each question.
What is the bond between two oppositely charged ions?
The ionic bond involves a transfer of electrons. The metal atom loses one or more electrons to form a positive ion (cation). The nonmetal atom gains one or more electrons to form a negative ion (anion). The attraction between these two oppositely charged ions is known as ionic bond.
How to find the number of electrons in an atom?
For neutral atoms, the number of electrons will be equal to the atomic number for that element. Place those electrons in shells until you have used up all the electrons. Begin with the innermost shell - it only gets 2 electrons as discussed in the previous section.
How many electrons does sodium have?
A sodium atom has a total of 11 electrons - 2 in the innermost shell, 8 in the second shell, and one lone electron in its valence shell . To fill its valence shell, it would need to acquire 7 electrons - a difficult task for a metal like sodium that is a known electron-loser.
How many electrons does the innermost shell hold?
Each successively larger shell can hold more electrons. So the innermost shell has a single s orbital and can hold at most 2 electrons.
Where are electrons located?
All About Electrons, Shells, and Valence Electrons. We understand electrons to be located in regions of space surrounding the nucleus that we refer to as electron shells. There are a series of concentric electron shells surrounding an atom's nucleus, each of varying size. The shells themselves contain orbitals.
Where do the next 8 electrons go in the atom?
The next 8 electrons (electron #11-18) go in the third shell; again there are 8 places to put these. If there are still more electrons to place in shells, then start placing them in the fourth electron shell. This method works really well for the first 20 element.
Does oxygen gain electrons?
And so oxygen will be happy if it can gains 2 more electrons to have a full octet of outer shell electrons. If it does, then it becomes a 2- ion: the O 2- ion. So non-metals such as fluorine and oxygen gain electrons in order to achieve a full octet of valence shell electrons.
