What is the ionic bond ?
The element is composed of the molecules , Each molecule consists of the atoms , The atom is electrically neutral in its ordinary state ( In the atom , the number of the electrons equals the number of the protons , The atoms combine with each other forming the molecules through the chemical bonds .
The ionic bond
The ionic bond is a type of chemical bonds that occur between a metal atom and a nonmetal atom , The ionic compounds are formed from a metallic cation and a non-metallic anion .
The metal atom loses electrons and changes into a positive ion , the nonmetal atom gains the electrons which lost from the metal atom and changes into a negative ion .
A strong electrostatic attraction between the positive and the negative ions occurs through the ionic bond , The ionic bond is a bond resulting from the electric attraction between a positive ion and a negative ion .
The ionic bonds produce the compounds only not the elements as the ionic bond arises between two different elements ( the metal and the nonmetal ) , The ionic bonds produce the ionic compounds only , and it has one type .
The ionic bond is formed by losing and gaining of the electrons , and it is formed between 2 atoms of two different elements .
The metals with few electrons in its outer-most orbital , by losing those electrons , these metals can achieve noble-gas configuration .
Nonmetals that have close to 8 electrons in its valences shell tend to accept electrons to achieve noble gas configuration .
The characteristics of the ionic compounds
The ionic compounds are solids at room temperature , they have high melting and boiling points , they dissolve in the water .
They do not conduct the electricity ( when they are solids ) , and they conduct electricity ( when they are liquids ) .
