Question

What type of bonding is represented in figure 2-2?

Answer 1

Answer:

Type of bonding is represented in the figure is Ionic bonding.

Explanation:

$Na^++Cl^-\rightarrow NaCl$

Type of bonding shown in the given figure is an Ionic bonding.

Ionic bonding is defined as bonding in which complete transfer of electrons takes place. Atom which looses electrons is known as electropositive atom and an atom which gains electrons is known as electronegative atom.

Sodium is the 11th element of the periodic table:

$[Na]=1s^22s^22p^63s^1$

Chlorine is the 17th element of the periodic table:

$[Cl]=1s^22s^22p^63s^23p5$

Sodium atom will donate an electron to gain noble gas configuration and chlorine atom needs an electron to gain noble gas configuration.

Answer 2

The bond is ionic because Na+ gave Cl- an electronic.
Giving electrons is ionic and sharing is covalent.
