A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms the bond is caused by the electrostatic force of attraction between opposite charges, either between electrons and nuclei, or as the result of a dipole attraction. A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds the bond may result from the ( . Why form chemical bonds the basic answer is that atoms are trying to reach the most stable (lowest-energy) state that they can many atoms become stable when their valence shell is filled with electrons or when they satisfy the octet rule (by having eight valence electrons).

Start studying 8th grade chapter 8 elements and chemical bonds learn vocabulary, terms, and more with flashcards, games, and other study tools. Answer: when a chemical bond is formed by the complete transfer of electrons from one atom to another, so as to complete their outermost shell and therefore, aquire the stable noble gas configuration, the bond formed is called ionic bond or electrovalent bond. The number of valence electrons in an atom of an element determines many properties of the element, including the ways in which the atom can bond with other atoms true false.
