Which type of bond results from the sharing of electrons between two atoms with similar electronegativities?

The type of bond that results from the sharing of electrons between two atoms with similar electronegativities is a covalent bond. In covalent bonding, atoms come together and share pairs of electrons, allowing each atom to attain a more stable electron configuration, typically resembling that of the nearest noble gas. This sharing occurs between nonmetals where the difference in electronegativity is minimal, which enables a more equal distribution of electron density between the involved atoms.

In contrast, ionic bonds occur between atoms with significantly different electronegativities, where one atom donates an electron to another, leading to the formation of charged ions that attract each other. Coordinate covalent bonds involve one atom providing both electrons in the shared pair, which typically happens when one atom has a lone pair of electrons. Lastly, metallic bonds do not involve electron sharing between individual atoms but rather involve a 'sea of electrons' that are free to move among a lattice of metal cations, contributing to the conductivity and malleability of metals.
