Differences between ionic and covalent bonding?

Answer 1

Elements in an ionic bond have a greater electronegativity difference (greater than 2.0), and there is always one metal involved. The electrons in an ionic bond are actually transferred from one element to another. Since this makes one element a negatively charged anion and the other a positively charged cation, the elements are now very strongly attracted to each other. This means that they have higher melting and boiling points, because it takes more energy to break the bonds between them. Ionic materials don't form molecules, but instead are all interconnected in a crystal lattice. For this reason, an ionic compound is expressed using the empirical formula, which gives the lowest ratio of the elements involved.

In a covalent bond, the electronegativity difference is less than 2.0, and the electrons are shared between the two elements, sometimes equally and sometimes not depending on if the bond is polar or nonpolar. Since they are not as strongly attracted (except in the case of a coordinate covalent bonds), they do not have high melting/boiling points. Covalent materials do form molecules, and so use molecular formula.

Hope that helps (and that it's not too much information!)

Answer 2

A covalent bond is a sharing of electrons in the outer shell. An ionic bond is a bond formed by the attraction between two oppositely charged ions.
ionic bond - atoms are bound together by oppositely-charged ions. covalent bond - atoms are bound by shared electrons
Both are chemical bonds

Ionic Bond: one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion

Covalent Bond: shares a pair of electrons between atoms in a molecule
A covalent bond is a chemical bond that forms when two or more atoms share electrons and an ionic bond is a strong chemical bond that results from the transfer of electrons between atoms.
The bond formed by transferring of electrons is called ionic bond.

if electronegativity difference between 2 elements is 1.7 or greater that 1.7 it is called ionic bond.

in other words if constituent elements are metal and non-metal it is ionic bond.

The bond formed by sharing of electrons is called covalent bond.

if the electronegativity difference between 2 elements is below 1.7 the bond formed is covalent bond.

Eg. MgCl2 is a compound by elements Magnesium and Chlorine.

electronegativity value of Magnesium is 1.2

electronegativity value of Chlorine is 3.0

so their difference is 1.8

greater than 1.7

so bond formed is ionic bond.

Answer 4

whats difference between covalent and ionic bonding

Answer 5

An ionic bond is formed by the TRANSFER of electrons whereas a covalent bond is formed by the SHARING of electrons.

Answer 6

Covalent bonds are formed by sharing of valence electrons and ionic bonds are formed by electrostatic bonds between ions.
