By exchanging electrons with one another, atoms create new materials. When two atoms share at least one pair of electrons, this is known as a covalent link. Ionic bonds form when positive are attracted to one another and share an electron as a consequence.
When two atoms share , they establish a connection. Because the two positively charged atomic nuclei and shared, negatively charged electrons in a covalent bond are attracted to one another by electrostatic forces, the bond is stable.
One or more pairs of electrons from each atom are shared by the other atoms to form a covalent link. The two atomic nuclei are pulling these electrons in opposite directions. When the gap between two atoms' electronegativities is too narrow for an electron transfer to take place and form ions, a covalent bond is created.
Reactants interact with one another in a chemical reaction, breaking the bonds that hold their atoms together.
