Question

What type of chemical bond holds the na+ and cl- ions together in table salt?

Answer 1

$\boxed{{\text{Ionic bond}}}$ holds ${\text{N}}{{\text{a}}^ + }$ and ${\text{C}}{{\text{l}}^ - }$ together in table salt.

Further Explanation:

Chemical bond:

The attraction between atoms, molecules or ions which results in the formation of chemical compounds is known as a chemical bond. It is formed either due to electrostatic forces or by the sharing of electrons. There are many strong bonds such as ionic bonds, covalent bonds, and metallic bonds while some weak bonds like dipole-dipole interactions, London dispersion forces, and hydrogen bonding.

Ionic compound:

Ionic compounds are the compounds that are formed from the ions of the respective species. Ions are the species that are formed either due to loss or gain of electrons. A neutral atom forms cation by the loss of electrons and anion by the gain of electrons.

Following are some of the properties of ionic compounds:

1. These are hard solids.

2. High melting and boiling points.

3. Good conductors of heat and electricity.

4. High enthalpy of fusion.

Sodium (Na) is a metal while chlorine (Cl) is a non-metal. So Na loses one of its valence electrons by virtue of its low ionization enthalpy and ${\text{N}}{{\text{a}}^ + }$ is formed. Due to high electronegativity of chlorine, Cl gains an electron and forms ${\text{C}}{{\text{l}}^ - }$ . The electrostatic attraction between ${\text{N}}{{\text{a}}^ + }$ and ${\text{C}}{{\text{l}}^ - }$ results in the formation of ionic bond between them and thus NaCl is an ionic compound.

Answer 2

The bond between Na + and Cl- ions is an ionic bond

To achieve stability, atoms with low ionization energy such as Na atoms will release electrons and bind to atoms with high-affinity energy such as Cl atoms

$\boxed{\boxed{\bold{Further~explanation}}}$

Atoms have different stability. Unstable atomic atoms will try to form stable electron configurations like those of noble gases. Where noble gases have the number of outer electrons 2 or 8

The formation of electron configurations such as noble gases can be done by forming shared ions or electron pairs

Atoms with high ionization energy and atoms that are difficult to draw electrons will form bonds with shared electron pairs (electrons can be from one atom or two atoms attached)

In forming ions, atoms will release or attract electrons

Ion bonds occur because atoms that have low ionization energy (easily release electrons) form a + ion, and these electrons are bound by atoms that have large affinity energy (easily pulling electrons)

Generally, ionic bonds occur in metal and nonmetallic elements. Metal elements have low ionization energy and non-metallic elements have a high electron affinity

In Na atoms, to achieve stability, Na will release one electron so that it has an electron configuration like noble gas Ne

Na: 2 8 1

Ne: 2 8

so that it becomes a Na + ion

While the Cl atom will bind one electron, so it has an electron configuration like noble gas Ar

Cl: 2 8 7

Ar: 2 8 8

So that it becomes a Cl- ion

Finally, there will be an attractive attraction between positive ions and negative ions and NaCl is formed

So the bond between Na + and Cl- ions is an ionic bond
