This is an ideal covalent bond - possible only between identical atoms of an element (H2).
Between atoms of two elements a difference of electronegativity exist always.
The difference between the electronegativities of the atoms is near zero.
covalent bonds.
is the line between elements in a chemical bond
A covalent bond is formed between two atoms with similar electronegativity.
The electrons get shared between the two elements, from the covalent bonds.
no
A metallic bond is a bond between two metals from the same group.
A metal and a non-metal.
It is called a "metallic bond"
ionic
If the difference in electronegativity is from 0.6 to 1.7, the bond will be polar and covalent.
If the difference in electronegativity between the elements is greater than 2 then the bond will be ionic, if its between 1.6 and 2 then it will be ionic if one of the elements is a metal.
