Ionic and Covalent Bonds

-Covalent bond: bond in which one or more pairs of electrons are shared by two atoms -Ionic bond: bond in which one or more electrons from one atom are removed and attached to another atom

In chemistry, a molecule and compound is formed when two or more atoms connect to each other via a chemical process known as bonding. There are two types of chemical bonding covalent and ionic.

Most covalent compounds have relatively low melting points and boiling points.The strength with which each atom pulls on shared electrons is called its electronegativity. When the pull between atoms is unequal we have a polar covalent bond.The pull between atoms is equal which is a non-polar covalent bond.

An ionic bond is when electrons are transferred between atoms of opposite charge. Ionic bonds invole non-metals and metals.A physical characteristic of an ionic bond is that theyconduct electricity in their molten state.Ionic bonds are a neutral charge.

A example of an ionic bond is sodium chloride known as table salt. Sodium is a positive ion (Na+) while chlorine is a negative ion (Cl-).An example of a nonpolar covalent bond is the bond between two hydrogen atoms because they equally share the electrons.
