Electronegativity. Atoms are neutral, but they want a complete valence shell, so some atoms attract other atoms and share their electrons so that both can have complete outer shells. In ionic bonding, the electron is actually transferred from one atom to the other, and both will have complete outer shells. In other words, they bond to achieve noble gas configurations. For example, a hydrogen atom will bond with another hydrogen atom because they want 2 electrons in their outer shells, instead of 1, and by sharing their electrons, both atoms of hydrogen will have 2 electrons. An example of ionic bonding would be NaCl. The sodium atom donates an electron to the Cl, and they will both have a complete valence shell.

Covalent Bonds-Covalent bonding is a variety of chemical bonding between 2 non steel atoms that's characterised by making use of the sharing of pairs of electrons between atoms and different covalent bonds. A covalent bond is formed between 2 non-metals that have comparable electronegativities. Neither atom is "sturdy" sufficient to entice electrons from the different. For stabilization, they proportion their electrons from outer molecular orbit with others Ionic Bonds-Ionic bond, additionally extensive-unfold as electrovalent bond is a variety of bond formed from the electrostatic attraction between oppositely charged ions in a chemical compound. those forms of bonds happen in particular between a steel and a non steel atom. An ionic bond is formed between a steel and a non-steel. Non-metals(-ve ion) are "greater suitable" than the steel(+ve ion) and can get electrons very honestly from the steel. those 2 opposite ions entice one yet another and type the ionic bond. EG: Covalent: Methane (CH4), Hydro Chloric acid (HCL), which aspects are all nonmetals Ionic: Sodium chloride (NaCl), Sulphuric Acid (H2SO4 ) etc.

It depends on the electronegativity differences between rthe elements. Metals have low electronegativities, and nonmetals have high electronegativities. If elements of high and low electronegativity bond, the result is likely an ionic (donating-accepting) bond If they are close in electronegativity, the result is likely a polar covalent bind (electrons shared, but spend more time around the atom of higher electronegativity). In O2, Cl2, N2, Br2, I2, the electronegativities are identical, so the bonds are nonpolar covalent.

Calculating the difference of electronegativity values of two atoms causes covalent and ionic bonding.

All atoms seek their lowest energy state which occurs when they have an full outer shell of electrons. Atoms bond to fill their outer shells.
